1) Two clear solutions are placed in separate beakers. The first solution has a pH = 4, and the pH of the second solution is unknown. If the two solutions are mixed and the resulting solution has a pH = 7, describe the second solution.

pH = 10

Explanation:

pH = -log [H⁺]

A solution that is pH = 4 has a [H⁺] = 1x10⁻⁴M

As the mixture of the two solutions is pH = 7 (Neutral). The second solution must contain the exact amount of OH⁻ to neutralize the H⁺ of the first solution. That is [OH⁻]  1x10⁻⁴

And as pOH = -log [OH⁻]

pOH = -log 1x10⁻⁴

pOH = 4

Also, pH = 14-pOH

pH of the second solution must be:

14 - 4

m=9

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

hope this and sorry i could only come up with one answer!
