We’re being asked to calculate the mass of KHC8H4O4 required to react with 15 mL of 0.16 M NaOH solution.
For this problem, we need to do the following steps:
Step 1: Write and balance a chemical equation for the given reaction.
Step 2: Determine the mass of KHC8H4O4 needed.
Step 1: Since KHC8H4O4 and NaOH are ionic compounds, they form ions when dissociating in water.
The dissociation of the two compounds is as follows:
For KHC8H4O4: Potassium is from Group 1 so it has a charge of +1. This means HC8H4O4 has a charge of –1:
KHC8H4O4 (aq) → K+(aq) + HC8H4O4–(aq)
For NaOH: Sodium is from Group 1 so it has a charge of +1. The hydroxide ion has a charge of –1:
NaOH(aq) → Na+(aq) + OH–(aq)
How do you calculate the mass of KHC8H4O4 (molar mass=204.44 g/mol) that reacts with 15mL of 0.16 M NaOH solution ?
