In each of the net ionic equations below, select which type of arrow should be used. Buffer equilibrium: HC2H3O2 [Select ] H + C2H3O2 Neutralization of the buffer with a base: HC2H3O2 + OH- [Select ] C2H3O2 + H2O Neutralization of the buffer with an acid: C2H3O2¯ + H* [ Select ] * HC2H3O2

A chemical compound that releases H+ to a solution is abase while that accepts H+ and removes them from solution is an acid. Select one: True False

Be sure to answer all parts. Determine the pH and percent ionization for a hydrocyanic acid (HCN) solution of concentration 9.7 x 10-3 M. (K, for HCN is 4.9 x 10-10,) |× 10% (Enter your answer in scientific notation.) pH = percent ionization =

Titration is a process in which an unknown concentration of a solution reacts with a solution of known concentration (a standard solution). A titration involving the reaction between an acid and a base is called an acid-base titration. Watch the animation to learn about acid-base titration, in which an unknown concentration of an acid-base solution reacts with a standard acid-base solution of known concentration. 14 12 10 8 PH Equivalence point 2 40 mls 60 20 The end point of an acid-base titration is determined by the use of a pH indicator of some type. It is the point where the titration is physically stopped as indicated by a signal from the indicator being used. This could be a color change or a dramatic change in pH on a pH meter. The equivalence point of the titration occurs when stoichiometrically equal amounts of acid and base have been added to the solution. The equivalence point is the point where the reaction is complete. At the equivalence point, the addition of one excess…
