Degree of hardness :-
Today here in this blog we’ll discuss the degree of hardness of water so let’s begin very first we’ll try to understand what we think about when we hear the term hardness of water.
So while talking about the degree of hardness of water the thing which comes in our mind very first is the presence of equivalent amount of calcium carbonate in the water but it is important to know that the hardness of water can’t be represented in the form of calcium carbonate because calcium carbonate is insoluble in water and hardness is actually caused by bicarbonates, chlorides and sulphates of calcium and magnesium.
Calcium carbonate is used as a standard for reporting hardness of water is due to
Reasons for using calcium carbonate for determining the hardness of water.
- The very first reason is that the it’s (calcium carbonate) molecular weight is exactly 100 and equivalent weight is 50 (it is used due to the ease of the calculation)
- Also it is the most insoluble salt that can be precipitated in the water treatment process.
Hope the above mentioned information helps for understanding about the degree of hardness
Thankyou and have an amazing day.
