Kw Equation Calculator

Formula

The formula to calculate Kw is:

\[ Kw = [H3O^+] \times [OH^-] \]

Where:

\(Kw\) is the ion product of water
\([H3O^+]\) is the concentration of hydronium ions (mol/L)
\([OH^-]\) is the concentration of hydroxide ions (mol/L)

What is the Kw Equation?

The Kw equation represents the ion product of water, which is the product of the concentrations of hydronium ions \([H3O^+]\) and hydroxide ions \([OH^-]\) in water. It is a fundamental concept in chemistry, particularly in acid-base chemistry.

Example Calculation

Let's assume the following values:

\([H3O^+]\) = \(1 \times 10^{-7}\) mol/L
\([OH^-]\) = \(1 \times 10^{-7}\) mol/L

Using the formula to calculate Kw:

\[ Kw = (1 \times 10^{-7}) \times (1 \times 10^{-7}) = 1 \times 10^{-14} \]

The Kw is \(1 \times 10^{-14}\).
