a student combined equal amounts of two solutions. one solution had a ph of 2 and the other had a ph of 12. which would most likely be the resulting ph? 1 3 6 11

a student combined equal amounts of two solutions. one solution had a ph of 2 and the other had a ph of 12. which would most likely be the resulting ph? 1 3 6 11

Answer

Explanation:

Step1: Recall pH - H⁺ and OH⁻ relationship

pH = 2 means $[H^+]=10^{- 2}\ M$ (acidic solution), pH = 12 means $[OH^-]=10^{-(14 - 12)}=10^{-2}\ M$ (basic solution).

Step2: Consider equal - volume mixing

When equal volumes of an acid and a base with equal molar concentrations of $H^+$ and $OH^-$ are mixed, they neutralize each other completely.

Step3: Determine resulting pH

The resulting solution is neutral, and the pH of a neutral solution is 7. But among the given options, the closest value to 7 is 6.
