If you wanted to standardize an approximately 0.1 M solution of hydrochloric acid by titrating 10.00 mL (delivered from a pipet)with approximately 30mL of sodium hydroxide solution (delivered from a buret), what should be the approximate concentration of the sodium hydroxide solution?

concHCL= 3* conc NaOH concNaOH= 1/3 *.1M

Im sorry can you explain that? So is the concentration of NaOH .03?

bobpursley · Answer

If you take three times as much NaOH as the volume of HCl, the NaOH must be 1/3 the concentration of the HCl. Now, 1/3 of .1M is NOT .03M It is closer to .033333M
