Concept explainers
(a)
Interpretation:
If the given statement is true or false needs to be determined.
The given net ionic equation shows the tiration of NaF versus H2SO4
Concept introduction:
Titration is to determine the quantitative information of the unknown sample when a known volume and concentration of reactant is utilized. It is usually an acid-base reaction. The unknown solution is the titrantand the known volume of solution is the titrant.
(b)
Interpretation:
If the given statement is true or false needs to be determined.
The given reaction is a reaction between a strong acid and base.
Concept introduction:
Titration is to determine the quantitative information of the unknown sample when a known volume and concentration of reactant is utilized. It is usually an acid-base
(c)
Interpretation:
If the given statement is true or false should be determined.
The solution acts as buffer at equivalnce point.
Concept introduction:
Titration is to determine the quantitative information of the unknown sample when a known volume and concentration of reactant is utilized. It is usually an acid-base reaction. The unknown solution is the titrantand the known volume of solution is the titrant. At the equivalence point, the color of the indicator changes.
(d)
Interpretation:
If the given statement is true or false should be determined.
The pH of the solution is not changed if the solution at half-neutralizartion is diluted with water.
Concept introduction:
Titration is to determine the quantitative information of the unknown sample when a known volume and concentration of reactant is utilized. It is usually an acid-base reaction. The unknown solution is the titrantand the known volume of solution is the titrant. At the equivalence point, the color of the indicator changes.
