Answer 1

Here are the answers for your questions:

**Question 10**
Which of the following is a characteristic of an acid?
**b. donates protons**
Acids are defined as proton donors in the Brønsted-Lowry acid-base theory. They can also taste sour, but that is not a defining characteristic.

**Question 11**
Which of the following is a characteristic of a base?
**c. feels slippery**
Bases typically feel slippery or soapy to the touch and are known for accepting protons (according to the Brønsted-Lowry definition), but the most iconic characteristic is their slippery feel.

**Question 12**
A solution with a pH of 9 would be acidic.
**False**
A pH of 9 is slightly basic, as anything above 7 is considered basic.

**Question 13**
A substance with a pH of less than 7 is a base.
**False**
A pH of less than 7 indicates that the substance is acidic, not basic.
