Question

If two solution having ph = 5 and ph = 7 of equal volume mixed together then what is the ph of mixture?

Answer 1

Answer:

pH = 4.3

Explanation:

H+ concentration = M1*V1 + M2V2 / V1+V2

so H+ = M1 +M2 /2

= 10^-5 +10^-7

= 5.05 * 10^-5

so pH = -log ( H+)

= 5 - log(5.05)

= 4.3

plz mark it brainliest.
