What is the ph of a solution with a concentration of 5.2 × 10–8 m h3o+?

Answer : The pH of a solution is, 7.28

Solution : Given,

Concentration of hydronium ion, =

pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.

Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.

Therefore, the pH of a solution is, 7.28

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
