Question

The  scale for acidity is defined by  where is the concentration of hydrogen ions measured in moles per liter (M).A solution has a  of 6.35.Calculate the concentration of hydrogen ions in moles per liter (M). Write the answer in scientific notation.

Answer 1

Hello, Dakota,

You have the formula we need to determine [H⁺]:

pH = -log₁₀[H⁺]

6.35 = -log₁₀[H⁺]

log₁₀[H⁺] = -6.35

This means: 10^-6.35

Use a spreadsheet or calculator to find this value. I get 2.24x10⁶ (Molar)
