# The Hydrogen Ion Concentration of a Vinegar Solution

## How is the hydrogen ion concentration of a vinegar solution represented in scientific notation?

**1.0 x 10^-4 M**. Therefore, the correct representation of the hydrogen ion concentration of a vinegar solution in scientific notation is

**1.0 x 10^-4 M**.

The hydrogen ion concentration of a vinegar solution is 0.00010 M. How is this concentration written in scientific notation?

The correct option is, 1.0 x 10^-4 M. Explanation: Scientific notation is a way of representing very large and small numbers. In scientific notation, a number is written as a number between 1 and 10 multiplied by a power of 10. The given number 0.00010 M is written as 1.0 x 10^-4 M in scientific notation.
