Chemistry- Acids, Bases, and Buffers Define Acid - correct answer A proton donor. Define Base - correct answer A proton acceptor. Why is H+ a Proton - correct answer Because hydrogen is just one proton and one electron. Take away the electron and you're left with H+. Define Alkali - correct answer A type of base which dissolves in water to form OH- ions (a soluble base). What is a Monobasic Acid and Give an Example of One - correct answer A monobasic acid e.g. HCl is an acid which ...

`Buffers - ANSWER-contains significant amounts of a weak base and its conjugate acid or weak acid and conjugate base Characteristics of buffers - ANSWER--resist pH change -weak acid neutralizes added base -weak base neutralizes added acid Common Ion Effect - ANSWER-Tendency for a common ion to decrease the solubility of an ionic compound or to decrease the ionization of a weak acid or a weak base Henderson-Hasselbalch equation - ANSWER-pH=pKa + log(base/acid) Buffer has weak acid ...

Experiment #: 5 Title: Buffers Purpose: The purpose of this lab is to determine how buffers affect the pH of a solution in order to observe how a buffer is resistant to pH changes. Additionally, we determined how enzymes activity is affected by pH. Procedure: Part 1: Determine pH of sodium acetate in water & buffer 1. 2 pH electrodes are place in 2 separate beakers, one filled with tap water & one is filled with a pH 7 buffer (both have an approximate pH of 7) 2. A scoop of sodium aceta...
