The acid base reaction equation is as follows;
HCl + NaOH ---> NaCl + H₂O
stoichiometry of HCl to NaOH is 1:1
NaOH is a strong base and HCl is a strong acid they completely dissociate into its ions
number of HCl moles - 0.16 mol/L x 0.200 L = 0.032 mol
number of NaOH moles - 0.091 mol/L x 0.300 L = 0.0273 mol
Limiting reactant is NaOH therefore number of HCl moles reacted - 0.0273 mol
the excess amount of HCl moles are - 0.032 - 0.0273 = 0.0047 mol
since HCl is a strong acid
total volume - 200 mL + 300 mL = 500 mL
[HCl ] = [H⁺]
therefore [H⁺] = 0.0047 mol / 0.500 mL
[H⁺] = 0.0094 mol/L
hydroxide ion concentration - 0.0094 M
Answer:
The volume of hydrochloric acid increases.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
- Increasing the volume of water vapors:
will increase the the concentration of the products side, so the reaction will be shifted to the left side (backward) to suppress the increase in the concentration of water vapors by addition.
So, The volume of hydrochloric acid increases, the rate of backward reaction increases, the rate of forward reaction decreases, and the volume of chlorine decreases.
<em>So, the right choice is: The volume of hydrochloric acid increases.</em>
