Question

WHAT IS HEAVY WATER, HARD WATER AND SOFT WATER?

Answer 1

Heavy Water :- Water in which the hydrogen in the molecules as partly or wholly replaced by the isotope deuterium, used especially as a moderator in nuclear reactors.

Hard Water :-  Water that has high mineral content. Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates.

Soft Water :- Water which has relatively low concentration of calcium carbonate and other ions. The water that lathers with soap easily is called soft water.

$\large\bold{\orange{{QUESTION}}}$

What is heavy water, hard water and soft water ?

$\large\bold{\orange{{ANSWER}}}$

$\small\bold{\blue{{HEAVY~WATER}}}$

Heavy water is a form of water that contains only deuterium rather than the common hydrogen-1 isotope that makes up most of the hydrogen in normal water. 

$\small\bold{\pink{{SOME~INFORMATION}}}$

▪ Formula: D2O

▪ Boiling point: 101.4 °C

$\small\bold{\blue{{HARD~WATER}}}$

Hard water is water that has high mineral content. Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. 

$\small\bold{\pink{{pH~LEVEL~OF~HARD~WATER}}}$

8.5

Water is considered hard when the pH level is above 8.5. Hard water does not pose a health risk, but can cause aesthetic problems such as: Bitter taste to the water and beverages such as tea or coffee.

$\small\bold{\blue{{SOFT~WATER}}}$

Soft water is surface water that contains low concentrations of ions and in particular is low in ions of calcium and magnesium. Soft water naturally occurs where rainfall and the drainage basin of rivers are formed of hard, impervious and calcium-poor rocks.
