What do you understand by temporary hardness of water?

Temporary hardness is water hardness due to the presence of calcium and magnesium carbonates and bicarbonates, which can be precipitated by heating the water. It can be removed by processes such as boiling or lime softening, and then separation of water from the resulting precipitate.

What do you understand by permanent hardness?

Permanent hardness refers to the mineral content in water that is not possible to remove through boiling. The hardness is typically caused by the presence in water of magnesium sulfates and/or calcium sulfate that do not undergo precipitation at increased temperatures.

What is hardness explain temporary and permanent hardness?

Temporary hardness is due to the soluble salts of magnesium and calcium in the form of hydrogen carbonates. and this hardness can be removed from water by boiling. Permanent hardness of water is due to the presence of soluble salts of calcium and magnesium in the form of chlorides in water.

What is temporary and permanent hardness of water mention which ion causes the hardness of water?

Temporary hardness of water : Presence of calcium, Magnesium bicarbonates in water causes temperory hardness. Permanent hardness of water : Presence of calcium, magnesium chlorides, sulphates in water causes permanent hardness. → Ca+2, Mg+2 ions mainly cause the hardness of water.

What do you understand by permanent water?

Hard water that cannot be softened by boiling; water containing magnesium sulfate or calcium sulfate.

What is the other name of temporary and permanent hardness?

Answer : Temporary and permanent hardness are also known as carbonate and non-carbonate hardness.

What is temporary hardness class 11?

1) Temporary hardness : Temporary hardness of water is due to the presence of bicarbonates of calcium and magnesium, i.e. Ca(HCO3)2 and Mg(HCO3)2 . It is called temporary hardness since it can be easily removed by boiling and filtering the water. Temporary hardness is also called carbonate hardness.

What is permanent hardness of water class 10?

Permanent hardness is due to the presence of magnesium and calcium are present in the form of sulphates and chlorides salts in water. We cannot remove them by boiling, thus, it is called permanent hardness. Permanent hardness can be removed by treating the water with washing soda.

What are temporary and permanent hardness of water what are their causes explain any two methods for the removal of permanent hardness of water?

The presence of magnesium and calcium carbonates in water makes it temporarily hard. In this case, the hardness in water can be removed by boiling the water. When we boil water the soluble salts of Mg(HCO3)2 is converted to Mg(OH)2 which is insoluble and hence gets precipitated and is removed.

What is hardness units of hardness and difference between temporary and permanent hardness?

Welcome back.

Temporary Hardness	Permanent Hardness
Temporary hardness can be largely removed by boiling when bicarbonates are decomposed yielding insoluble carbonates on hydroids.	Permanent hardness cannot be removed by boiling.

What is temporary hardness and permanent hardness class 11?
