Thank you ☺️☺️☺️
t doesn't represent the concentration of AgCl dissolved in water because we assume that AgCl dissociates into Ag+ ions and Cl- ions when it dissolves in water. It can't represent the amount of solid AgCl in the system because the equilibrium is not affected by the amount of excess solid added to the system.
Answer
Hi, the correct answer is,
B. It is an acid-base reaction because the sodium hydroxide base reacts with the hydrochloric acid to form a salt and water
Explanation
When an acid reacts with a base, the products are salt and water.In this case, sodium hydroxide is a base which contains hydroxide ions, OH-, whereas hydrochloric acid is an acid that has Hydrogen ions, H+.When they react, they form sodium chloride, NaCl in aqueous solution as the salt , and additional water molecules. The equation is;
NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l)
Explanation:
Let us assume that the ratio for the given reaction is 1:1.
Therefore, we will calculate the moles of 
as follows.
Moles of solution = molarity × volume (L)
= 0.0440 M × 0.014 L
= 0.000616 moles
Moles of excess EDTA = 0.000616 moles
Also, the initial moles of EDTA will be calculated as follows.
Total initial moles of EDTA = 0.0600 M × 0.025 L
= 0.0015
Therefore, moles of EDTA reacted with 
will be as follows.
= 0.0015 - 0.000616
= 0.00088 moles
Since, we have supposed a 1 : 1 ratio between and EDTA
.
So, moles of = 0.00088 moles
Now, we will calculate the molarity of as follows.
Molarity of solution = 
= 
= 0.015 M
Thus, we can conclude that the original concentration of the solution is 0.015 M.
