Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution

A1 forms when an acid is neutralized by a base. 1. salts can be neutral, or in solutions. salts of 2. strong acid–strong base reactions produce solutions with 3. water. salts formed from the neutralization of weak acids or weak 4. bases water. they produce solutions that are acidic or . basic. for example, the ph of a solution at the equivalence point is . greater than for a acid titration. solutions that resist changes in ph are called solutions. the buffer is the amount of acid or base that can be added to a buffer without changing the ph greatly.
