Equivalents, Electroneutrality, Water Hardness

Use the same data from Example $1$

Cations:

Anions:

Total hardness $(TH)=$ polyvalent cations $=$

Carbonate hardness $(CH)=$ carbonate and bicarbonate

Noncarbonate hardness $(NCH)=$ Total hardness $-$ carbonate hardness $[$or zero if $CH>TH]$

$NCH=$

Look back at Example $2$ on page $3.$ Determine the water hardness for that water sample.

Total hardness $(TH)=$ polyvalent cations

Carbonate hardness $(CH)=$ carbonate and bicarbonate $=$

Noncarbonate hardness $($NCH$)=$ Total hardness $-$ carbonate hardness $[$or zero if $CH>TH]$

$NCH$ :
