Calcium The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns.
Identify the effect of increasing acidity on the solubility of …
Calcium phosphate solubility is pH dependent. At lower pH, calcium phosphate is more soluble in water while at pH above 8.5, the solubility of calcium phosphate decreases markedly. For Barium hydroxide and magnesium carbonate,decreasing the pH will increase the solubility of the compound.

Indium - Wikipedia
Indium metal does not react with water, but it is oxidized by stronger oxidizing agents such as halogens to give indium(III) compounds. It does not form a boride, silicide, or carbide, and the hydride InH 3 has at best a transitory existence in ethereal solutions at low temperatures, being unstable enough to spontaneously polymerize without coordination.
