1 Provide a term that matches each description below a Most common measure of solution acidity b Substance that readily donates a proton c Solution that resists a pH change when acid or base is added d Two substances related to each other by the presence of a single H e Substance that readily accepts a proton 2 Calculate the pH of each of the following solutions, and label each as acidic, basic, or neutral. Solution [H30+] = 1.0 x 10° M [H30+] = 0.001 M [H30')-3.7 × 10-6 M pH Acidic/Basic/Neutral A student measured the mass of one dose of a store brand antacid tablet to be 0.750 g. The studer the tablets and used 0.126 g to neutralize a solution of acid. What percentage of the antacid tablet to neutralize the acid solution? Show your work. Circle all of the pairs of compounds below that represent a conjugate acid-base pair. a H2S/HS c Ca(OH)2/CaSOExplanation / Answer
1)
a) Most common measure of acidity - pH
b) Substance that readily donates a proton - Acid
c) Substance that resists the pH when acid or base is added - Buffer
d) Two substances related each other by the presence of single H+ - Conjugate acid base pair
e) Substance that readily accepts a proton - Base
