Ans 4 :
Since solubility of gases is inversely related to the temperature at a constant pressure , so increasing the temperature to 60oC will decrease the solubility of CO2 in water.
Since the solubility of CO2 in water is decreased , the rate of formation of carbonic acid in water will also decrease.
So the pH of the water will increase.

(8 pts) Carbon dioxide in the atmosphere dissolves in water to establish an equilibrium that can increase the acidity of aqueous solutions in the environment. This equilibrium is CO2 (g) ⇌ CO2 (aq), Kh = 3.1 * 10^2 at 25°C. Kh is called the Henry’s law constant, which relates the solubility of the gas CO2 in the aqueous solution, [CO2], to the partial pressure of CO2 over the solution, p(CO2): [CO2] (M) = Kh * p(CO2) (atm) During the preceding...

This equilibrium is CO2(g) = CO2 (aq), Kn= 3.1 x 10-2 at 25°C. Kh is called the Henry's law constant, which relates the solubility of the gas CO2 in the aqueous solution, [CO2), to the partial pressure of CO2 over the solution, p(CO2): [CO2] (M)= Kn · p(CO2) (atm) During the preceding decades, the atmospheric...

Question 2 a. Estimate the pH of distilled water produced in Jebel Ali desalination plant if the concentration of CO2 in the atmosphere is about 300 ppm assuming water temperature is 25 °C. Write your assumption clearly b. Assuming, due to increasing air pollution (especially at the vicinity of the gas combustion turbines and generators), the concentration of CO2 increases to 800 ppm in Jebel Ali Free Zone. Therefore, desalinated water reaches equilibrium according to this condition. Comment on the...

1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...
