Question

What is the concentration of hydrogen ions in a solution of ph = 4.0 ASAP PLEASE

Answer 1

Answer:

concentration of H  ions = 0.0001 M

Explanation:

Base 10 logarithm of the H+ concentration when multiplied by -1 is equal to the pH value of a solution. By reversing this formula, we can find the concentration of the H+ in the solution:

pH = $-$㏒ $(concentration of H+)$

or $10^{-pH} =$ = concentration of H+

We know that, pH of the solution is 4.0,

so $10^{-4}$ = $0.0001$

Therefore, the concentration of Hydrogen ions in a solution of pH = 4 is 0.0001 M.
