KEY POINT 1 A pH between 0 and 7 is acidic a pH of exactly 7 is neutral a pH between 7 and 14 is basic KEY POINT 2 The more free unattached H ions there are in a solution the more acidic it is KEY POINT 3 HCO3 is a buffer that makes pH less acidic by absorbing H ions in the blood so they re not free anymore KEY POINT 4 The kidneys control the amount of H excretion and amount of HCO3 conservation in the body in order to maintain the pH of the blood 1 If the pH of a system is rising is it becoming more acidic or more basic 2 Does that mean that it has more or less H ions 3 Does that mean that the kidney wants to excrete more or less H ions
