How to calculate hydrogen ion concentation from pH

pH - (log) [H+]

Explanation:

Find the Hydrogen ion concentration;

then the logarithm of that concentration, and change the sign.

If [H+] = 1 x /10 to the negative 7 (moles per liter), the log of that is -7, the opposite of that is 7

Ergo, pH 7. IF the acid is very very concentrated, the pH can be negative. This was a very easy one I chose that you likely saw in class, but work on a few more, and it will be easy. When the acids are very very weak disassociation, you will need another, little bit harder equation. Just remember what pH is; “the opposite of the log of hydrogen (or Hydronium ion) concentration.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
