Unformatted text preview: ©2010 Digital Interactive Video Education Week 25 128 LESSON 48: TITRATIONS, BUFFERS Assignment: 1) Read textbook pages corresponding to this topic. 2) Defne the ¡ollowing terms: Salt, neutral salt, acid salt, basic salt, titration, titration curve, equivalence point, end point, buffer 3) Watch lecture and take notes. 4) Complete review questions, and check answers. LESSON 48 REVIEW QUESTIONS Solutions are at the end o¡ the video ¡or this lesson. 1-4 3 pts each. Record numerical answers using signifcant digits. 1) Describe the di¡¡erence between neutral salts, acid salts and basic salts. 2) Describe what a bu¡¡er does to maintain a constant pH. 3) 60.0 ml o¡ a 0.10 M solution o¡ HCl was titrated with 87.9 ml o¡ NaOH. What was the concentration o¡ NaOH? 4) 33.5 ml o¡ Mg(OH) 2 were required to neutralize 100.0 ml o¡ 0.20 M HCl. What was the concentration o¡ the Mg(OH) 2 ? Neutral salts result from the reaction of strong acids and bases, acid salts result from the reaction of strong acids and weak bases, and basic salts result from the reaction of weak acids and strong bases. A buffer is an amphriprotic substance, meaning it can act as an acid or a base. When acid is added, the buffer acts as a base and accepts the acid’s protons and neutralizes it. When base is added, the buffer acts as an acid and donates a proton to neutralize the accepts the acid’s protons and neutralizes it....
