Correction: pH=-log[H+] * Chemistry. 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 as defined as pH = Very acid corresponds to pH values near 1, Neutral corresponds to a pH near 7 (pure water), and Very basic corresponds to values near 14. If the wine has an approximate hydrogen ion concentration of 5.01×104 , calculate its pH value.
