In this lab, lab 4.3 Comparing the Concentrations of Saturated Solutions, we set out to find and compare the solubilities of two solids in water. In addition, we tested if solubility is a characteristic property of a solid in a given liquid. This lab allowed us to test and use a reliable way to measure the solubility of a solid. This lab can be replicated for any solid with the same procedure, thus it gives us a method to calculate solubility. The two solids we tested in this experiment were NaCl (Sodium Chloride) and NaNO3 (Sodium Nitrate).
Potatoes have become a staple to the diet of humans.They have become so popular since they come in a variety of shapes, sizes, and tastes. They are also cheap and easy to grow, and they taste delicious! Potatoes have changed the course of history in several ways. Who knew that potatoes, just a starchy vegetable, could have helped shape the world in so many ways. First, the Irish Potato Famine killed a million people and caused another million to move out of Ireland. Second, soldiers in the United States army were able to eat potatoes throughout the war. Third, they prevented a famine from occurring in England after there was not a sufficient amount of crops going to sustain the country's cries for food. Many people wonder if potatoes have
We started by cutting the potato in pieces and weighing them until they weighed at 200 grams. While the potatoes were being done, we filled the blender with 2 handfuls of ice and 200 ml. of cold distilled water. Then we mixed the potato pieces, ice and 200 ml. of cold distilled water for about 15-20 seconds at high speed. I then grabbed the 1000 ml. beaker so I could pour the solution from the blender and place it in the ice bath. Next we took the 4-40 ml. beakers and labeled them A-D. The other 4-40 ml beakers were marked as 1-4.
The potato is the storage part of the plant and so this is where the
We cut three potato chips to an equal length and then we set up 3
Determining the Concentration Of Limewater Solution Aim: The aim of this experiment is it to find out the concentration of Limewater by performing a titration with hydrochloric acid which has concentration exactly 2.00M.. What is required for me is that I have to design my own experiment and chose the right and appropriate apparatus and equipment. I will be provided with 250cm3 of limewater, which has been made to which contains approximately 1g/dm3 of calcium Hydroxide. This hypothesis from www.studentcentral.co.uk We were also give Hydrochloric acid (HCl) with a concentration of 2.00 mol/dm3 normal laboratory apparatus was also given and so was an indicator.
I will need 3 pieces of potato in each tube. As there are 6 tubes I

Determining the Concentration of a Lime Water Solution Planning I am provided with 250cm3 of limewater which has been made such that it contains approximately 1gdm3 of calcium. Also available is hydrochloric acid which contains exactly 2.00 mol dm-3 I am to determine the concentration of limewater solution by Titration method. Apparatus used is as follows: * 50ml burette * 100ml conical flask * 100ml beaker * white tiles * resort tiles * safety goggles * pipette Chemicals used are: · 250cm3 of limewater which contains approximately 1g dm-3of CaOH · HCL solution (2.00 mol dm-3) · Distilled water · Methyl orange used as an indicator Firstly put the alkaline calcium hydroxide solution in the flask and the hydrochloric acid in the burette. Next you need to construct the relevant equation: Ca(OH)2 + 2HCl ----> CaCl2 + 2H2O
4. Put each group of potato discs in one of the 6 test tubes and watch
The Effect of Salt Solution Concentration On The Mass Of Potatoes Introduction = == == == ==
Determining the Concentration of a Limewater Solution Introduction Previous to conducting my experiment, research was carried out and the results of it adapted to aid me in solving the problem set. In the Advanced Chemistry Student’s Book by Nuffield, on page 86, I found a similar experiment to mine with a description of implementation, which aided me in the fact that I discovered the temperature of my solution did not need to be taken. This was because the solution of calcium hydroxide they used was saturated, and therefore they measured the temperature of the saturated solution along with its solubility, due to the fact that the solubility of saturated substances varies with temperature. This procedure will not be necessary in my particular experiment as the solution I will use will be far from saturated. Safety measures were observed and taken into account by looking at the hazard card for calcium hydroxide.
