CHEM 2001 : Exam 3 Garno 2014 Key
Document Summary
Kb = 10 pkb = 10-9. 81 = 1. 5488 x 10-10 = 1. 55 x 10-10. Question 2. (5 pts) list three strong acids and two strong bases. Strong acids: hcl, hbr, hi, h2so4, hno3, hclo4. Write the acid dissociation expressions and the equilibrium equations for ka1 and ka2 for sulfuric acid, h2so4. There will be two equivalence points, because sulfuric acid is diprotic. Identify the type of titration from the plots below (strong acid, strong base, weak acid, weak base, etc. ) Please clarify which is the solution and which is the titrant. Strong acid added to a weak base weak acid added to a strong base strong acid added to a strong base. + h2o h3o + + so4. Donald found that 20. 0 ml of 0. 10 m naoh neutralized 25. 0 ml of hydrochloric acid. Determine the concentration of the acid. (show your work and the formulas you used for your result). Write the balanced chemical equation for the reaction:
