Calcium - Element information, properties and uses | …
Our drinking water also contains calcium ions - more so in so called hard water areas. Hard water is the term used for water with a high proportion of calcium and magnesium (2 plus) ions. The calcium usually enters the water as it flows past either calcium carbonate, from limestone and chalk, or calcium sulfate, from other mineral deposits.
Reactions of the Group 1 elements with water
2020/8/19· There are also changes going on with the water present - turning it into hydrogen gas and hydroxide ions. To get the total enthalpy changes, you would have to add these values in as well. The changes due to the water will, however, be the same for each reaction - in each case about -382 kJ / mol. Adding that on to the figures in this table gives the values in the previous one to within a kJ or
