Eww! This reminds me of school.

I HAVE A QUESTION!

A 500mL bottle of concentrated sulfuric acid (18molL-1) was dropped in a laboratory accident. Solid sodium hydrogen carbonate (NaHCO3) was used to neutralize the spilled acid.

a) Justify the choice of the solid sodium hydrogen carbonate to clean up the spill. Include relavent equaltions(s).

b) Calculate the minimum mass of sodium hydrogen carbonate needed to neutralise the spilled acid completely.



Good luck guys!

(HINT: question a is worth 4 marks and question b is worth 3.)
