Question

a.)Watch the animation and observe the titration process of a standard 0.100 M sodium hydroxide solution with 50.0 m ml of a 0.100 M hydrochloric acid solution. Identify which of the following statements regarding acid-base titration are correct.
Check all that apply.

The titration process is based on a chemical reaction.
The m pH of the solution at the equivalence point is 7.
At the endpoint, the m pH of solution is 10 and the color of solution is pink.
At the beginning of the titration process, the m pH of the solution increases rapidly.
The chemical reaction involved in an acid-base titration is a neutralization reaction.
Before any base is added to the solution, the m pH of the solution is high.
In a titration process, the endpoint is reached before the equivalence point.
The m pH of the solution changes very slowly at the equivalence point.

b.)100 m mL of 1.00 M~ m HCl solution is titrated with 1.00 M~ m NaOH solution. You added the following quantities of 1.00 M ~ m NaOH to the reaction flask. Classify the following conditions based on whether they are before the equivalence point, at the equivalence point, or after the equivalence point/endpoint.

Drag the appropriate items to their respective bins.


c.)60.0 mL of a 0.450 M m HNO_3 solution is titrated with 0.570 M m KOH. Calculate the volume of m KOH required to reach the equivalence point.
Especially c



Explanation / Answer

a) The pH of the solution at the equivalence point is 7. At the end point , the pH of the solution is 10 and the color of the solution is pink The chemical reaction involved in an acid-base titration is a neutralization reaction. b) Before: 50.0ml, 5.00ml, 10.0ml Equivalence: 100ml After: 200ml,150ml c) 0.450M*60.0ml/.570M=47.4ml
