Here are the answers to the questions based on general chemistry concepts:
**Question 10**
Which of the following is a characteristic of an acid?
**d** donates protons
**Question 11**
Which of the following is a characteristic of a base?
**b** feels slippery
**Question 12**
A solution with a pH of 9 would be acidic.
**False** (pH 9 is basic)
**Question 13**
A substance with a pH of less than 7 is a base.
**False** (pH less than 7 indicates an acid)
**Question 14**
In a solution of salt water, the salt is the:
**d** solute
**Question 15**
When a solution has the maximum amount of solute dissolved, it is said to be saturated.
**True**
**Question 16**
When a solution has more than the maximum amount of solute dissolved, then it is said to be:
**d** supersaturated
**Question 17**
In a solution of salt water, the water is the:
**c** solvent
**Question 18**
A solution of 40 grams of KCl at 50 degrees Celsius is ________________.
This would depend on the specific solubility curve for KCl at 50 degrees Celsius, but generally:
**b** saturated (assuming 40 grams is the maximum solubility at that temperature; if it is more, then it could be supersaturated)
**Question 19**
Which of the following will increase the solubility of a solute? (Select all that apply)
**b** heating the solution
**d** stirring the solution
**e** increasing the surface area of the solute
Cooling the solution (a) would generally decrease solubility for most solids, and decreasing the surface area (c) would also typically decrease solubility.
