Answer:
This question lacks options, the options are:
A. 1
B. 3
C. 6
D. 11
The answer is C. 6
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.
