The solubility of a gas in a solvent changes when pressure is applied. Click on the image to explore this activity, which illustrates the relationship between the pressure (P) and the solubility (S) of a gas. In this activity, you can see a sealed container of water and Ny gas. Click on the Run button to see the relative changes in the solubility of N₂ gas in water as the pressure of the N₂ gas is increased and decreased. The values of the pressure and the solubility of gas are tabulated adjacent to the Run and Reset buttons in the activity Part A Click on the Run button in the activity. Watch how the solubility of a gas changes as pressure is increased and then decreased during the run Which of the following statements correctly explain the relationship between the solubility of a gas and its pressure?

Question 2 Answer all the question below, 1. In one gravimetric analysis, a sample that weighed 0.810g is analysed for its phosphorous (P) content by precipitating the phosphorous as Mg,P2O. The precipitate is filtered, washed and weighed. The mass of the precipitate is found to be 0.4250 g. a) Why must the precipitate be washed? b) Calculate the percentage of P. 2. In one gravimetric analysis, the aluminum in a 1.2g sample of impure NHAI(SO4)2 was precipitate as hydrous ALO3.XH2O. The precipitate was filtered and ignited at 1000 °C to give anhydrous Al203 which weighed 0.1798g. Calculate the % Al inthe sample. 3. A sample of 0.4500g impure potassium chloride was dissolved in water treated with excess silver nitrate solution. 0.8402 g of silver chloride was precipitated. What is the percentage of potassium chloride in the sample?
