• What Gets Left Behind On The Bottom Of The Limewater Container?The solids on the bottom of a limewater reservoir contain everything that did not dissolve, or that dissolved and later precipitated from solution. Such solids could contain magnesium hydroxide and carbonate, calcium hydroxide and carbonate (though calcium hydroxide is fairly unlikely in unsaturated limewater) and a variety of other impurities, such as alumina, silica, etc.
