In chemistry, pH is a measure of the acidity or basicity of an aqueous solution. Which of the following explanations is correct?
a) The pH of distilled water is zero.
b) The higher the concentration of hydrogen ion, the higher the value of pH.
c) The pH of a hydrochloric acid solution is higher than that of the aqueous solution of sodium hydroxide.
d) The concentration of hydrogen ions in a solution with pH is times higher than that of a solution with pH .

Correct them! a) The pH of distilled water is 7
b) The higher the concentration of hydrogen ion, the LOWER the value of pH
c) The pH of hydrochloric acid is LOWER than that of the aqueous solution of sodium hydroxide
More to know: Another unit we can use to test the acidity or basicity is pOH. Opposite with pH, pOH=-log[OH-]. Moreover to remember, pOH = 14 - pH in the same solution!
