Hydrogen and Hydroxide Ion Calculation

What is the formula for calculating Kw?

• Kw = [H+][OH-] + [H2O]

• Kw = [H+][OH-]

• Kw = [H+][OH-] + [H2O2]

• Kw = [H+][OH-] - [H2O]

What is the value of Kw at 25 degrees Celsius?

• 1.0 x 10^-14

• 1.0 x 10^-12

• 1.0 x 10^-13

• 1.0 x 10^-15

If the hydroxide ion concentration is 1.0 x 10^-7 M, what is the hydrogen ion concentration?

• 1.0 x 10^-7 M

• 1.0 x 10^-6 M

• 1.0 x 10^-14 M

• 1.0 x 10^7 M

If the hydrogen ion concentration is 1.0 x 10^-3 M, what is the hydroxide ion concentration?

• 1.0 x 10^-1 M

• 1.0 x 10^-5 M

• 1.0 x 10^-7 M

• 1.0 x 10^-11 M

If the hydrogen ion concentration is 1.0 x 10^-9 M, what is the hydroxide ion concentration?

• 1.0 x 10^-5 M

• 1.0 x 10^-7 M

• 1.0 x 10^-10 M

• 1.0 x 10^-14 M

If the hydroxide ion concentration is 1.0 x 10^-5 M, what is the hydrogen ion concentration?

• 1.0 x 10^-9 M

• 1.0 x 10^-3 M

• 1.0 x 10^-7 M

• 1.0 x 10^-11 M

What is the relationship between hydrogen ion concentration and hydroxide ion concentration in an acidic solution?

• Hydrogen ion concentration is lower than hydroxide ion concentration.

• Hydrogen ion concentration is higher than hydroxide ion concentration.

• Hydrogen ion concentration is equal to hydroxide ion concentration.

• Hydrogen ion concentration has no relationship with hydroxide ion concentration.
