Question

Acetic acid, found in apple acid and apple butter, can cause explosions when heated in aluminum pans. If 250 mL of a 4 M solutions of acetic acid were used with plenty of aluminum then how many moles of hydrogen gas would be produced

Answer 1

hen acetic acid reacts with aluminum, the following reaction occurs:

2 CH3COOH + Al -> Al(CH3COO)2 + H2

The number of moles of acetic acid can be calculated using the formula:

moles = (concentration) x (volume) = (4 M) x (0.25 L) = 1 mole

Since 2 moles of acetic acid react with 1 mole of aluminum to produce 1 mole of hydrogen gas, we can calculate the number of moles of hydrogen gas produced:

moles of H2 = 1 mole / 2 = 0.5 moles.

So, 0.5 moles of hydrogen gas would be produced when 250 mL of a 4 M solution of acetic acid is used with plenty of aluminum.
