Standard Solution?? (1 Viewer)

[n00bl3t]

I have a question about a question from Conquering Chem:
"Suppose you wanted to determine the percentage purity of a sample of washing
soda, sodium carbonate decahydrate, that you had just purchased. Your laboratory has a solution of hydrochloric acid labelled 0.25 mol/L. It also has the usual range of pure chemicals and indicator solutions, an accurate mass balance and a full range of volumetric glassware. Explain fully how you would accurately determine the percentage purity of the washing soda."

Would the HCl be the standard solution in this scenario?? Would this question require making a primary standard?
Please excuse my stupidity

the standard solution is the HCL(the solution that has a known concentration)
it is the "standard" ie what everything is compared to.
