Hard water has high concentrations of Ca2+ and Mg2+ ions dissolved in it. Boiling the water causes these ions to come out of the water as lime scale. However it does not remove all the ions causing hard water. To do this you need to pass the water though a 'de-ionising' filter.

A water softener helps filter out these particles.
Can you change a hard boiled egg to its original soft inside?
No you cannot change a hard boiled egg into its original state. You would have to make another egg. If you want a soft boiled egg, you would put the egg or eggs in a small pot covering the egg or eggs with cold water. Put a lid on the pot and wait for the water to boil (put burner on medium to high). Once the water has boiled, immediatly time the egg for 3 min, and once the 3 min is up, dump out hot water and rinse eggs with cold water to stop the egg from over cooking. Then crack open the top of the egg and enjoy!
