Answer:
Volume of HCl = 0.0688 L
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
So, pH = 1.3
Thus, 1.3 = - log [H⁺]
[H⁺] = 0.05012 M
Since, HCl is a strong acid, the concentration of HCl = 0.05012 M
Also,
Moles of :-
Mass =
Also, 1 mg = 0.001 g
So =, Mass =
Molar mass of = 58.32 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction:-
1 mole of neutralizes 2 moles of HCl
Considering:
So,
Thus,
Appyling values as:-
<u>Volume of HCl = 0.0688 L</u>
The following chemical formulas would require a prefix when is it named, Cl207
