Lime Softening

10/07/25

“How can we use lime to remove magnesium and calcium ions from water?”

Water with an overabundance of magnesium and calcium ions requires water softening to prevent soap scum buildup. One way to accomplish this is to add limewater (calcium hydroxide) to the water to raise its pH level, forcing the magnesium and calcium to precipitate out by bonding with carbonate molecules. This process, often referred to as Lime Softening, is an effective way to soften water for practical use.
