Problem: Elixirs such as Alka-Seltzer use the reaction of sodium bicarbonate with citric acid in aqueous solution to produce a fizz:3 NaHCO3 (aq) + C6H8O7 (aq) → 3 CO 2 (g) + 3 H2O (l) + Na 3C6H5O7 (aq)What mass of C6H8O7 should be used for every 1.0 x 10 2 mg NaHCO3?

FREE Expert Solution

Concept: Stoichiometry.

Use the balanced equation to find moles of C6H8Ofrom moles of NaHCO3.

But first convert mass of NaHCOto moles.
