Acid-Base Equivalents are used to measure the number of H+ ions or OH- ions in acids and bases, respectively.

###### Understanding Acid-Base Equivalents

Concept #1: Understanding Acid-Base Equivalents

Concept #2: Calculating Acid-Base Equivalents

Example #1: Calculate number of Equivalents in each of the following:

a) 1 mole of H3PO4                     b) 2.7 g of RbOH

Concept #3: Equivalent Weight

Example #2: Calculate the equivalent weight of H2SO4.

Concept #4: Normality

Example #3: Calculate Normality of each of the following solutions:

a) 4.6 x 10-2 M NaOH                             b) 0.35 g of H3POin 1 L

Practice: Calculate mass (grams) needed for the following base equivalent: 0.18 mEq of Mg(OH)2.

Practice: Identify the acid that possesses an equivalent weight of 63 grams.

Practice: Determine volume (mL) needed to prepare a 0.73 g of Ca(OH)2 solution with 1.25 N.
