Application +4 | -1

A sample of hard water containing

{Ca}^{2+}(\mathrm{aq})

ions, having concentration

400 \, \mathrm{ppm}

is passed through cation exchange resin

({RH})

which exchanges

{Ca}^{2+}(\mathrm{aq})

ions for

{H}^{+}(\mathrm{aq})

. What is the volume of

1 \, \mathrm{M}

{NaOH}

required to neutralise

1 \mathrm{~L}

of water obtained from cation exchange resin after exchange of

{Ca}^{2+}

of hard water?

View answer and explanation

Correct option: A

20 \mathrm{~mL}

Option A (20 mL) is correct because the volume of NaOH required is calculated based on the concentration of Ca2+ ions and the stoichiometry of the neutralization reaction.
