Question 1
Calculate the pH of a 1.0 × 10−6M solution of HNO3
Question 2
Calculate the pH of a 1.0 × 10−1M solution
of NaOH
Homework Answers
1)
[H+] = [HNO3] = 1.0*10^-6 M
use:
pH = -log [H+]
= -log (1.0*10^-6)
= 6.00
Answer: 6.00
2)
[OH-] = [NaOH] = 1.0*10^-1 M
use:
pOH = -log [OH-]
= -log (1.0*10^-1)
= 1.00
use:
PH = 14.00 - pOH
= 14.00 - 1.00
= 13.00
Answer: 13.00
