I put tablet C as the amount it neutralised was higher and the amount of acid must = the amount of active ingredient

Yes it was! :biggrin:
I thought it only fizzes when it goes under thermal decomposition? And the question was about it reacting with sulfuric acid?

Yes it worked faster but the question was asking which is the most effective and tablet c neutralised 50cm3 wheras b neutralised only 25cm3

i think it fizzes when the reaction produces a gas, and it produced CO2 right?

Calm down mate it's really quite simple. It's C because the amount used to neutralise MUST EQUAL the amount neutralised
