Answer : The pH of the solution is, 1.31
Explanation : Given,
Mass of = 248 mg = 0.248 g (1 mg = 0.001 g)
Volume of solution = 140 mL
Molar mass of = 36.5 g/mole
First we have to calculate the concentration of hydrochloric acid.
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
The concentration of HCl is, 0.0485 M
As we know that, HCl dissociates to give hydrogen ion and chloride ion.
The dissociation reaction is:
Concentration of HCl = Concentration of H⁺ = Concentration of Cl⁻ = 0.0485 M
Now we have to calculate the pH of the solution.
pH : It is defined as the negative logarithm of hydrogen ion concentration.
Mathematically,
Therefore, the pH of the solution is, 1.31
There are more reactants than the products
Explanation:
For any system in equilibrium, the molar concentration of all the species on the right hand side is related to the molar concentrations of those at the left hand side by a constant known as the equilibrium constant (K).
The constant is temperature dependent.
- When the equilibrium constant is less than 1, it implies that there are more reactants than the products.
- If the constant is equal to 1, the products and reactants are the same.
- If the constant is greater than 1, the products are more than the reactants.
