IF 1.5 MOLES OF OXYGEN REACTS WITH SULPHUR (IV) OXIDE, CALCULATE THE MASS OF TETRAOXOSULPHATE(VI) ACID PRODUCED
To calculate the mass of tetraoxosulfate (VI) acid produced when 1.5 moles of oxygen reacts with sulfur (IV) oxide, we need to determine the balanced chemical equation for the reaction first. The balanced equation is as follows: 2SO2 + O2…
REASONS WHY ORGANIC SUBSTANCES ARE USUALLY RECRYSTALLIZED AFTER THEY HAVE BEEN PRODUCED
Organic substances are frequently recrystallized after they have been produced for several reasons. Recrystallization is a purification technique commonly used in organic chemistry to remove impurities from a solid compound. By dissolving the compound in a suitable solvent and then…
