\(\mathrm{RH}_{2}\) (ion exchange resin) can replace \(\mathrm{Ca}^{2+}\) in hard water as follows.\[\mathrm{RH}_{2}+\mathrm{Ca}^{2+} \rightarrow \mathrm{RCa}+2 \mathrm{H}^{+}\]One litre of hard water after passing through \(\mathrm{RH}_{2}\) has \(\mathrm{pH}=2\). Hence, hardness in ppm of \(\mathrm{Ca}^{2+}\) ishttps://bit.ly/YTAI_PWAP https://www.pw.live
