The water wouldn't form lather(foam) with soap,it would waste soap. It could be cold because most hard water are cold. Solution is boiling,using detergents because it dissolv es than solid or bar soap.
You might be talking about ice but hard water is sourced from limescale rock and the limescale is in the water and that is what you get in your kettle when you dont filter the hard water.
Forms of Calcium is what makes hard water hard
Hard water is potable (drinkable).
How can we deal with hard water
No. There is different types of hard water.There is slightly hard, moderately hard, hard and very hard water.And as for soft water it has to have less than a grain of calcium or magnesium. Hard water isn't as useful as soft water.
hard water is which has no ability to lather with soap standard hard water contains 1mg of calcium carbonate in every 1ml of water.

chemistry involved in Hard water
Forms of Calcium is what makes hard water hard
Hard water does not produce lather. So soap does not work effectively with hard water as soap does not form a good lather with hard water.
Hard water has more calcium than soft water does
hard water can be converted to soft water by boiling, filteration etc.
