CaCO₃ required
3.16 g
Moles H⁺
0.0631 mol
Water volume
1,000 L
CaCO₃ in kg
0.0032 kg
Formula and working
moles H+ = 10^(-pH) × volume(L); mass CaCO3 (g) = moles H+ ÷ 2 × 100.09
- 1
Collect the inputs
Water volume = 1,000 L; Acid rain pH = 4.2
- 2
Apply the formula
moles H+ = 10^(-pH) × volume(L); mass CaCO3 (g) = moles H+ ÷ 2 × 100.09
- 3
Result
CaCO₃ required = 3.16 g
