Calculate the mass of nitric acid required to neutralize 7.4 grams of calcium hydroxide.
| July 7, 2021 | education
The neutralization reaction between nitric acid and calcium hydroxide proceeds with the formation of calcium nitrate and water. The reaction equation can be written as:
2 HNO3 + Ca (OH) 2 = Ca (NO3) 2 + 2 H2O
The molar mass of nitric acid is 63 g / mol; the molar mass of calcium hydroxide is 74 g / mol.
According to the reaction equation, we will compose the proportion:
X g of nitric acid corresponds to 7.4 g of calcium hydroxide, as
2 * 63 g / mol of nitric acid corresponds to 74 g / mol of calcium hydroxide.
X = (7.4 * 2 * 63) / 74 = 12.6 g of nitric acid
Answer: 12.6 g of nitric acid
