The number of H+ in 1 c.c solution of pH 13 is__________________?
Correct answer: C. 6.023 x 10^7
- A. 6.023 x 10^13
- B. 6.023 x 10^10
- C. 6.023 x 10^7
- D. 1013
Explanation
At pH 13, the hydrogen-ion concentration is 10^-13 mol/L. One cubic centimetre is 10^-3 L, giving 10^-16 mol or approximately 6.023 × 10^7 hydrogen ions.
