Question

What is the concentration of hydrochloric acid if 0.1m/dm^3 of sodium hydroxide is used, and 32ml^3 is used of it to make the titration occur?

Answer 1

We want the quotient...`"molarity"="moles of solute"/"volume of solution"`

Explanation:

And we interrogate the reaction...

`HCl(aq) + NaOH(aq) rarr NaCl(aq) + H_2O(l)`..

Now we can work out the moles of sodium hydroxide...i.e.

`0.1*mol*dm^-3xx32xx10^-3*dm^3=3.20*mmol`.

Now there is equimolar `HCl`, BUT, we DO NOT KNOW the volume in which the hydrogen chloride coreactant was dissolved...and so there are insufficient data...
