How is degree of hardness calculated in terms of CaCo3 & why? give two reasons.
Answers
Answer:
As mentioned, the degree of hardness is expressed as parts per million (ppm) and thus may be defined as the number of parts by weight of CaCO3 (equivalent to Mg salts) present in a million (106) parts by weight of water. It is given that 1 kg of water contains 24 mg of MgSO4.

Answer:
this question is hard but I will tel
Ca has one degree
Co3 has also 1 degree
because it the degree is not shown above
and this is a balanced equation sooo
hope it is helpful ❤️❤️❤️
good morning
have a nice day ❤️
