Question

The pH of a solution ranges from 0 to 14. An acid has a pH less than 7. Pure water is neutral and has a pH of 7. The pH of a solution is given by pH = -logx where x represents the concentration of the hydrogen ions in the solution in moles per liter. Find the pH if the hydrogen ion concentration is 1 x 10^-1

Answer 1

A. 13

B. 1

C. -13

D. -1

Answer 2

1.

Answer 3

They give you this equation for the pH of a solution:
\[pH=-logx\]Where x is the concentration of hydrogen ions in mol/L. Since we know the concentration is 10^-1 mol/L we can plug it in for x:
\[pH=-\log(10^{-1})\]I'm going to assume here that the unspecified log is to the base 10. From here you just need to evaluate the right side.

Answer 4

is it chemistry?
