Question

A local company sent you their green alternative for window cleaner to be tested for percent (w/v) acetic acid content. For your experiment, you first standardized your NaOH titrant with 0.8053 g of (99.80 % purity) KHP. You used 40.60 mL of NaOH for your standardization. After that you then analyzed a 10.00 mL sample and found that you needed 43.20 mL NaOH to reach the end point.

Summary of results:

Standardization	Sample analysis
KHP Weight (g)	0.8053 g	Volume of sample	50.00 mL
Purity	99.80%	NaOH (mL) used	33.20 mL
NaOH (mL) used	40.60 mL

Determine the following:

Molarity of NaOH
% (w/v) acetic acid
