PRE-LAB (BUFFER!~) 1. Briefly describe the hazards associated with 0.1 M HCl and 0.1 M NaOH solutions. It is important to wear protections such as goggles, gloves, and aprons, to protect oneself from HCl and NaOH solutions. Although the chemicals are diluted, there is still the potential for burning along with the well-known fact that NaOH’ can easily damage tissues. (The lab precaution warns the students of the fact that the dilute solutions of sodium bicarbonate, hydrochloric acid, and sodium hydroxide are body issue irritants. Also we must always learn from Carol's mistake) 2. a) Using Equation 1 as a guide, write an equation for the reactions of acetic acid (CH 3 COOH) with water. Acetic acid is a familiar weak acid that is the primary ingredient in vinegar. b) Identify the conjugate base of acetic acid in the reaction equation. Hint: The H atom highlighted in boldface is the acidic or “active” hydrogen in acetic acid. CH
