Document Summary

Buffers- resist ph change by neutralizing added acid or base. A buffer contains significant amounts of both a weak acid and its conjugate base or a weak base and its conjugate acid. When adding addition base to a buffer the weak acid reacts with the base neutralizing it. When addition acid is added to buffer the conjugate base reacts with the acid neutralizing it. A buffer must contain significant amounts of both a weak acid and its conjugate base. They can resist strong acid and bases as long as the amount of strong acid or base is less than the conjugate. < a buffer contains significant amounts of both a weak acid and its conjugate base. 16. 3 buffer effectiveness buffer range and buffer captivity: An effecter buffer neutralizes small to moderate amounts of added acid or base. A buffer can be destroyed by adding too much acid or base. There are 2 factors that influence the effectiveness of a buffer.
