In chemistry, the pH of a substance is a measure of its acidity. The relationship between C, the hydrogen ion concentration in moles per liter, and p, the pH, is described by the equation below. C=10−p
A chemistry student has determined that the hydrogen ion concentration of vinegar is 0.00631 moles per liter. Which is closest to the pH of vinegar?
