Pro-Lab Study Questiona 1. What does the pH of a solution tell you? PH tells you whether a solution is acidic basic or neutral 2. What is neutralization? The Ht protons from the acid combine with the OH-hydroxide jons from the base to produce water (420), the remaining substance, 3. What is a buffer? a Sant Buffer maintain the PH of isolution by reacting with small amounts of acids or bases...
