Explanation:
Answer: 2.25
Explanation: 1:1 mole ratio seen in equation.
Answer:
2.5 × 10–5 M H3O+ and 4.0 × 10–10 M OH–
Explanation:
pH = - log[H3O+]
Therefore;
pH = - log[H3O+] = 4.6
Hence;
[H3O+] = 10^-4.6
= 2.51 ×10^-5 M
= 2.5 ×10^-5 M
Additionally;
pH + pOH = 14
Thus; pOH = 14 -pH
= 14 -4.6
= 9.4
but; pOH = - log [OH-]
Therefore;
[OH-] = 10^-9.4
= 3.98 × 10^-10 M
= 4 × 10^-10 M
