I'm trying to understand the difference between a lime juice added to alcoholic beverages (such as Rose's Lime) to sweet and sour mix. Some drinks require one while other drinks requires the second. I bought the store brands - the sour mix is horrible. So, trying to make my own lime juice and sour mix - all the recipes on line are the same for both. The more I try to research it, the more I'm confused.
Molecules are actually not unavoidably can no longer dissolve in water, sugar can dissolve in water. HCl could be ionized in water, meaning that H and Cl are separated by using polar action of water molecule.. it is the reason it is soluble.
Lime is CaO. (Sometimes referred to as quicklime.) It is produced from limestone, CaCO3, by heating it and driving off CO2. The limestone comes from ancient sea shells. CaCO3(s) --heat--> CaO(s) + CO2(g) When CaO is combined with water we get slaked lime, which calcium hydroxide. It's true that calcium hydroxide is a strong base (and dissociates completely), it's also not very soluble in water. CaO(s) + H2O(l) --> Ca(OH)2(s) The mortar to which you refer, in reacting with CO2, is going back to where the lime originally came from, calcium carbonate. Carbon dioxide dissolves in water to make an acidic solution. The acidic solution react with the base, the calcium hydroxide, to produce calcium carbonate. CO2(g) + H2O(l) <==> H+ + HCO3- Ca(OH)2(s) + H+ + HCO3- --> CaCO3(s) + 2H2O(l) The catch is that calcium carbonate, the stuff of limestone, is soluble in the acid that is produced when carbon dioxide dissolves in water to make acid rain. It's also soluble in any other acid, like HCl. CaCO3(s) + 2H+ --> Ca2+ + CO2(g) + H2O(l) CaCO3(s) + 2HCl(aq) --> CaCl2(aq) + CO2(g) + H2O(l)
1) Ca(OH)2 + CO2 → CaCO3 + H2O 2) CaCO3 +2HCl → CaCl2 + CO2 + H2O It dissolves because the CaCl2 is soluble in water.
