Answer:

3.451 mL.

Explanation:

  • It is a dilution process.
  • We have the rule states that the no. of millimoles before dilution is equal to the no. of millimoles after dilution.

<em>(MV) before dilution = (MV) after dilution</em>

M before dilution = 5.0 M.

V before dilution = ??? mL.

M after dilution = 0.17 M.

V after dilution = 101.5 mL.

∴ The volume before dilution = (MV) after dilution / M before dilution = (0.17 M)(101.5 mL) / (5.0 M) = 3.451 mL.

Answer:

See explanation

Explanation:

A titration involves the addition of a titrant to an analyte solution. It is a method of volumetric analysis.

When a particular volume of titrant is added, the colour changes to signal the end point of the reaction.

The point at which the colour changes is called the equivalence point. This is the point at which the amount of titrant added is just enough to completely neutralize the analyte solution.

Hence the volume NaOH that needs to be added to the beaker containing HCl to cause a colour change is the volume of NaOH that is just enough to completely neutralize the HCl solution.
