Question

The pH scale measures whether solutions are acidic, basic, or neutral. The pH needed by living cells is very specific, and can vary only slightly. because all living things are made up of cells that are mostly water, the pH of cells is close to A) 7. B) 0. C) 14. D) the acidic range

Answer 1

I am pretty sure it's a or c

Answer 2

Answer:

7.

Explanation:

pH may be defined as the negative logarithms of hydrogen ion concentration. The pH scale is used to determine the acidity and the basicity of the proteins on the pH scale.

Acids has the pH less than 7 whereas the base has the pH more than 7. Since, the cell contains large amount of water, its pH is 7. Water is a neutral molecule and neutral substances has pH nearly equal to 7 when measured on the pH scale.

Thus, the correct answer is option (A).
