The ph of 10-8 m solution of hcl in water is
WebbCalculate 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 … WebbExample #1: Here's a variant that's not framed in a tricky way: Show that the pH of a solution remains 7.00 when 1.0 x 10¯ 11 moles of HCl is added to the solution. Solution: 1) pH of 7.00 means this: [H +] = 1.0 x 10¯ 7 M. 2) Add 1.0 x 10¯ 11 moles of H + to get: 1.0001 x 10¯ 7 M pH = −log 1.0001 x 10¯ 7 = 6.9999566 3) Round the answer off to two …
