Creating a the liquid fertilizer Experiment Chemistry 1065 10/09/2012 Introduction The aim of this experiment was going to create a liquid fertilizer that contain Nitrogen, potassium and phosphorus, each element had to have 8% mass percentage. We were as well required to put an additional component, magnesium and it mass percentage needed to be 1 . 5%.

At the end with the experiment, the pH of your aqueous option had to be among 6. zero and several. 0.

As a group, be it natural or processed we expected that we wasn’t able to successfully produce the liquefied fertilizer with the compounds i was provided with, because some of the ingredients would build a precipitate if mixed. As a result we decided that it would be take further experimentation of trying different combination of these types of compounds in small scale to aid us successfully create the necessary fertilizer. This kind of experiment is important because it is necessary to make a plant fertilizer that is environment-friendly and that supplies various plant life with the nutrition they need to develop.

This research was interesting because provided us the opportunity to see get involved the perspective from the scientists whom constantly keep working towards making the ideal fertilizers for plants. Recent attempts simply by scientists of making the ‘ideal fertilizer include failed because either the fertilizer is not environment-safe or this increases the birth-rate of agricultural pests. From this lab, all of us created several compound combos to try and match the compounds in the necessary fertilizer.

A number of our combinations worked, however, many failed. We made adjustments to the unique information offered to all of us in order to satisfy the standards from the required liquid fertilizer, so that as a group we tried the best to indicate such adjustments throughout our lab studies so that the visitor can be more informed regarding the test we performed.. Experimental Since our conjecture was that a number of the provided substances would not to get an aqueous solution, we all decided to take a look at some mixtures on small-scale to see the way they reacted.

The compounds we needed for these kinds of combinations had been: Potassium carbonate, trisodium phosphate, potassium nitrate, ammonium carbonate, sodium phosphate, and salt nitrate. We also necessary some water to dissolve these compounds in. In order to execute a solubility evaluation on the offered compounds all of us obtained a proper plate, a spatula to incorporate the sturdy compounds in the well dish, a beaker full of distilled water, a pipette to incorporate water in to the well discs containing two different chemical substances, and a stirring pole to blend the mixture.

First utilizing a spatula we took a small amount of K2CO3 and put with the wells for the well plate. Then we-took a small sample of Na3PO4 and put this in the same well. By using a pipette we took 3ml of distilled water from the beaker and added it in to the well that contain K2CO3 and Na3PO4. The using a stir rod, we all continuously stirred the solution to get 1 tiny and we noticed. Then we-took small types of K2Co3 and NH4Co3 and set them in a second well around the well dish. Then all of us added 3ml of drinking water using a pipette. Using a stir rod, we all mixed the solution continuously for approximately a minute.

Subsequent we took tiny samples of NaNO3 and NaPO3 and put these questions third well on the well plate. We all added water using a pipette and stirred up the solution. Then we-took samples of NaPO3 and KNO3 and put these questions fourth well at the well plate. We added 3 ml of water, stirred the solution and observed. Following we took samples of Na2PO3, K2CO3 and NaNO3 and put these questions fifth well. We added 3ml of water, continuously stirred the solution and noticed. We after that took samples of Na2PO3, K2CO3 and NaNO3 and put these questions sixth well plate.

Then we added 3ml of water and constantly stirred the solution for any minute and observed. Through eliminating alternatives that created a medications we hand picked the solution that contain, Na2PO3, K2CO3 and NaNO3 as the solution that could possibly be our liquid fertilizer because it included nitrogen, phosphorus and potassium ions. Because we necessary nitrogen, phosphorus and potassium to each provide an 8% mass percentage in relation to the total option, we calculated how much of every compound all of us needed so that the three needed elements could have 8% mass percentage each in 10g of H2O.

We compute the amount of each compound necessary by first figuring it in moles and after that we changed it to grams. We replaced Na2PO3 with Na3PO4 because Na2PO3 was unavailable. After establishing how much of each and every compound we needed to generate our fertilizer, we made the decision that we needed a beaker, a level, weighing conventional paper, pH übung, graduated tube, stirring rod, Magnesium and H2SO4 to neutralize the solution by the end. We started by analyzing out some. 23481g of Na3PO4, 0. 707g of K2CO3, and 5. 8221g NaNO3. Then we poured the considered compounds into a beaker.

We then tested 10ml of distilled drinking water using a graduated cylinder. We all then put the 10ml water into the beaker containing our 3 compounds. By using a stirring rod we stirred the mixture for about 3 minutes. The compounds did not dissolve in water because the ratio from the compounds to the water wasn’t able to allow the ingredients to completely reduce in the normal water. With recommendations from our T. A we decided to split the amount of every one of the compounds by simply 10. The modern amounts of the compounds were: 0. 423481g of Na3PO4, 0. 0707g of K2CO3, and zero. 58221g NaNO3. We after that weighed out these fresh amounts of ingredients.

We put them into a new beaker and added 10 milliliters water. Utilizing a stirring rod, we continuously stirred the perfect solution is until the substances were totally dissolved. Subsequent we got a pH übung to gauge the pH of our solution. The pH of our solution needed to be between 6th. 0 and 7. 0. We connected the loggerpro software into a laptop and we the ph level collected was 12. 43. Since the fertilizer solution was a basic we chose to neutralize that using an acid. The amount of acid we chose to use was H2SO4. Using a pipette we all added drops of H2SO4 to our fertilizer solution as we monitored the pH of the solution.

It was a little while until 2 . 4ml of H2SO4 to bring the pH of the liquid fertilizer to 6. seventy five. To make the liquid fertilizer complete we were required to add an additional aspect, magnesium such that it had a 5% mass percentage. We chose to make use of the compound magnesium nitrate as it contains a magnesium ion. We determined that for magnesium to experience a 5% mass percentage inside the solution we all needed several. 05g of Mg (NO3)2. But mainly because we had divided the various other compounds in the solution by ten earlier, we had to divide how much Mg (NO3)2 paste to hold the same rate.

So after dividing the amount of magnesium necessary by 15 we lead with 0. 305g of Mg. We then weighed 0. 305g of Mg (NO3)2 on a scale plus the poured it into the beaker containing each of our aqueous option. Using a stir rod we all stirred the solution before the Mg (NO3)2 was totally dissolved. We all then completed the try things out by testing the final ph level of our answer which was 6. 7.
