Question

What is the pH of a 0.125 M NaOH solution?

Answer 1

more than 7

Explanation:

as NaOH(sodium hydroxide) is a strong base, which will result the ph value to be more than 7, That's why.

Answer 2

Answer:

(oH-)=0.125

pOH=-log10(OH-)

pOH=-log10(0.125)

pOH=–(-1.0969)

pOH=1–0.0969

pOH=0.9031

we know that pH+pOH=14

we know that pH+pOH=14 pH=14–0.9031

we know that pH+pOH=14 pH=14–0.9031 pH=13.0969
