Answer:
pH will always be less than 7
Explanation:
This is because NH3 is a relatively weak base and the resulting Acidic salt on titration might hydrolyse to form a buffer solution
Answer:
Equilibrium shifts to produce more reactant
Explanation:
- <em>Le Châtelier's principle</em> <em>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.</em>
- When more product is added to the solution:
<em>This will increase the concentration of the products side, so the reaction will be shifted to the lift side (reactants side) to suppress the increase in the concentration of Products.</em>
<em />
<em>So, the right choice is: Equilibrium shifts to produce more reactant</em>
