Standardisation of HCl

We are titrating HCl against Sodium Carbonate to find concentration of HCl. On question in the report asks if the sodium was not heated as it should be and had absorbed 2% of its mass in water would that be a random or a systematic error?

i cant decide. Thanks guys.

I think it is a systematic, cause if you can repeat the experiment again to get a correct value for your HCl concentration.
i may be wrong. hah

Yes it's systematic error. Experimental procedure is wrong.
