<u>Answer:</u> 0.0237 g of calcium carbonate would be required to neutralize the given amount of HCl
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen ion concentration present in the solution
.....(1)
Given value of pH = 1.5
Putting values in equation 1:
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(2)
We are given:
Volume of solution = 15.0 mL
Molarity of HCl = 0.0316 M
Putting values in equation 2:
The chemical equation for the reaction of HCl and calcium carbonate follows:
By the stoichiometry of the reaction:
2 moles of HCl reacts with 1 mole of calcium carbonate
So, of HCl will react with =
of calcium carbonate
The number of moles is defined as the ratio of the mass of a substance to its molar mass.
Moles of calcium carbonate =
Molar mass of calcium carbonate = 100.01 g/mol
Putting values in the above equation:
Hence, 0.0237 g of calcium carbonate would be required to neutralize the given amount of HCl
The reaction that has been, following the law of conservation of mass has been .
The law of conservation has been given in the chemical reaction that there has been no loss or gain of the mass and energy.
The law of conservation has been evident when there has been an equal number of atoms of each element on the product and the reactant side.
