Ph of 10–8 m hcl solution is nearly
WebCalculate the pH of 10 -8 M HCl. If we use the relation, pH = – log [H 3 O + ], we get pH equal to 8. But this is not correct because an acidic solution cannot have pH greater than 7. WebApr 4, 2024 · 10 − 8 M HCl solution is 6.98. Therefore, the correct option is C. Note: When we calculate the pH using the relation p H = − log [ H 3 O +], the pH obtained is 8 but the value …
