CH105: Consumer Chemistry
Take 10 mL distilled water in a test tube and take the same volume of hard water in another test tube. Add a few drops of soap solution to both the test tubes and shake well. Do both the test tubes contain the same quantity of foam? Which test tube contains more foam? What do you infer? Answer: No. Both the test tube does not contain same quantity of foam. Distilled water taken test tube contains more foam. Soap does not lather well in hard water. The hardness of water is due to dissolved calcium and magnesium salts in it. These salts react with soap to form insoluble compounds resulting in the decrease of lather. Question Take 10 mL each of hard water in two test tubes. Add a few drops of soap solution in the first test tube and add the same amount of detergent solution in the second one. Shake both the test tubes well. What do you observe? Answer: Soap does not lather well in hard water. But detergents do not give insoluble components on reaction with these salts. Hence detergents are more effective than soaps in hard water.

Chemistry Chapter 6 Test B Answer Key
List out the merits and demerits of detergents, compared to soaps. Answer: Detergents are more effective than soaps in hard water. Detergents are effective in acidic solutions. Demerits: excessive use of the detergents causes environmental problems. The microorganisms in water cannot decompose the components of detergents. Hence the detergents released into water lead to the destruction of aquatic life. For example, the detergents which contain phosphate increases the growth of algae and limits the quantity of oxygen. Therefore, it dej creases the quantity of oxygen for the breath of the organisms in water and causes their destruction.

Find the equilibrium pressure of all gases if Hydrogen gas is obtained from the natural gas by partial oxidation with steam as per the following endothermic reaction: Write the expression for Kp for the above reaction How will the value of Kp and composition of equilibrium mixture be affected by: i increasing the pressure, ii increasing the temperature, iii using a catalyst? Answer: The expression for Kp for the reaction is: i By increasing the pressure, the number of moles per unit volume will increase. In order to decrease the same, the equilibrium gets shifted to the left or in the backward direction. As a result, more of reactants will be formed and the value of Kp will decrease. Therefore, the equilibrium gets shifted to the right and the value of Kp will increase. But it will be attained more quickly.
