Question

What is the hydrogen ion concentration of a substance with a hydroxide ion concentration of 1.07x10-10M?

(Be sure to give your answer in 3 sig figs and the unit. Also type the letter "e" for "X10" just like on webassign
with no spaces)

Answer 1

Step-by-step explanation:

[OH⁻] = 1.07 x 10⁻¹⁰

[H⁺] x [ OH⁻ ] = 10⁻¹⁴

[H⁺] x 1.07 x 10⁻¹⁰ = 10⁻¹⁴

[H⁺] = 10⁻¹⁴ / 1.07 x 10⁻¹⁰

= .93458 x 10⁻⁴

= 9.3458 x 10⁻⁵

= 9.35 x 10⁻⁵

= 9.35e-5. M.
