Reaction of calcium with water; 5. 0 0. Bubbles of hydrogen gas are given off, and a white precipitate (of calcium hydroxide) is formed, together with an alkaline solution (also of calcium hydroxide, which is slightly water-soluble). Reaction of calcium with water. 6. CaO is calcium oxide, the white … 5 years ago. You will produce a small amount of hydrogen, but at the same time you would create a somewhat powerful base known as Calcium Hydroxide. Calcium oxide reacts with water in a combination reaction to produce calcium hydroxide: CaO (s) + H2O (l) → Ca (OH) 2 (s) In a particular experiment, a 5.50-g sample of CaO is reacted with excess water and 6.77 g of Ca (OH) 2 is recovered. Summary of the reaction between metals with cold water and steam; 10. Calcium, for example, reacts fairly vigorously and exothermically with cold water. Thanks. A portion of the sample is digested in a combination of acids. Ca(s) + 2H2O(l)→Ca(OH)2(aq) + H2(g) Bubbles form and you might see the metal splashing around before it dissolves. Calcium hydroxide is slightly soluble in water so once the solution is saturated, it starts to become milky as solid calcium hydroxide appear. Ca + H2O --> CaO + H2. Ask … Get your answers by asking now. Answer Save. Because Calcium reacts with water and formation of Calcium Hydroxide and Hydrogen gas takes place. Anonymous. Calcium reacts slowly with water, forming calcium hydroxide and hydrogen. Ca (s) + 2 H 2 O (l) Ca(OH) 2 (aq) + H 2 (g) Quantitative analysis. 11. Method 3500-Ca C Inductively Coupled Plasma Method [1]. The equation for the reactions of any of these metals would is as follows: 4. The reaction creates Hydrogen gas, H2 which are the bubbles.
