Expert Solution
Step 1
Potassium hydrogen phthalate will be represented as KHP for simplicity.
• The reaction between calcium hydroxide and KHP is shown below:-
Ca(OH)2+ 2KHP---> Ca(KP)2+ 2H2O .
• According to the equation, 2 mole of KHP reacts with 1 mole of Ca(OH)2. This is the stoichiometric ratio between KHP and Ca(OH)2 is 2:1 .
• First, the number of moles of Ca(OH)2 that reacted will be calculated (volumes converted to liters).
Moles of Ca(OH)2 = (0.402 M * 0.029 L )
= 0.011658 moles .
