Not knowing when crystallisation is complete: the reaction may be incomplete

Not proving that H2SO4 was a catalyst and doesn't actually participate in the reaction

Time constraints: Means u cannot scratch for as long as needed and that drying may be incomplete

Equipment: Since it is glass equipment, cannot scratch hard. Scales only have a certain accuracy

That's basically what I put down for my report =]
