The pH of a solution is a measure of the molar concentration of hydrogen ions, H* in moles per liter, in the solution, which means that it is a measure of the acidity or basicity of the solution. The letters pH stand for "power of hydrogen," and the numerical value is defined as pH = - log10[H*] Acidic solution corresponds to pH values near1, neutral solution corresponds to a pH near 7, and basic solution corresponds to values near 14. Classify each solution as acidic, neutral, or basic and determine its pH level.
