Water softening - Wikipedia

Water softening is the removal of calcium, magnesium, and certain other metal ions in hard water.The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of pluing by reducing or eliminating scale build-up in pipes and fittings. Water softening is usually achieved using lime softening or

Lab: Stoichiometry of a Precipitation Reaction

Jun 09, 2015· Measure 100 mL of distilled water and pour it carefully into the 250-mL beaker. Carefully add the sodium carbonate to the water using the metal scoop. Be sure no solid remains in the container you used to weigh it. Stir the mixture you have made until the sodium carbonate has completely dissolved. Measure 60 mL of the 1.0 M calcium chloride

Distillation removes oxygen and some trace metals from water. For this reason some people claim distilled water tastes flat. a calcium and magnesium scale will collect at the bottom of the boiling chaer. The scale eventually needs to be removed, usually by hand scrubbing or by using acid.

Water for mixing coolant? - Practical Machinist

Jul 03, 2011· I bought some Hocut 795 B coolant which is advertised to mix with hard or soft water. I do know our tap water has left some decent lime and calcium deposits in our water heater over the years but I dont know if that would bother coolant or not. I am only dealing with 10 gallons of coolant so using distilled water would be a possibility.
