1.	100 mLof tap water containing Ca(HCO3)2 was titrated with N/50 HCl with methyl orange as indicaor. If 30mL of HCl was required, the temporary hardness as part of CaCO3 per 10^6 parts of water is Explain with details
Answer» Milli EQUIVALENT of Ca(HCO 3 ) 2 = miili equivalent of CACO 3 = MILI equivalent of HClN 1 V 1 =N 2 V 2 1000×w/(100/2)= 30/50w= 0.03 gFor 100ml the amount of CaCO 3 =0.03 gFor 10 6 = 0.03×10 6 /100=300 ppmExplanation:hope it will helpfull follow me
