This question lacks options, the options are:

A. 1

B. 3

C. 6

D. 11

Explanation:

pH of a solution refers to the concentration of hydrogen ions in that solution. A scale is used to measure pH of a solution.

* A pH value less than (<) 7 is said to be ACIDIC. The lesser the number, the more acidic

* A pH value of exactly 7 is said to be NEUTRAL

* A pH value above (>) 7 is said to be BASIC OR ALKALINE. The higher the number, the more alkaline.

According to this question, two solutions of equal volume with pH values of 2 and 12 respectively were combined. Based on the explanation of pH scale, the solution with pH 2 is said to be very ACIDIC while the solution with pH 12 is said to be very ALKALINE.

Hence, if this two solutions are combined, a neutralization will occur which will result to a solution with close to neutral pH (7). In the above options, 6 is the closest pH value to NEUTRAL and hence, the most likely pH of the resulting solution.
