Yes, it does.
The metal, Cobalt dissolves slowly in dilute sulphuric acid to form solutions containing the aqueous Co(II) ion together with hydrogen gas, H2.
The equation is:
Co (S) + H2So4 (aq) ---> Co^+2 (aq) + So4^-4 (aq) + H2 (g)
When excess cobalt oxide is warmed with hydrochloric acid, the cobalt oxide will react with the acid to form cobalt chloride, water, and chlorine gas. The resulting solution may be pink due to the presence of cobalt ions, which are often a characteristic color of cobalt compounds.
CoCO3 (Cobalt II carbonate) would be a weak base.
The name of the acid is carbonic acid (H2CO3).
Germanium does not react with hydrochloric acid at room temperature. However, it can react with hydrochloric acid when heated, forming germanium chloride.
Hydrogen does not react with water. In an acid, hydrogen can react to form hydrogen gas and a salt.
When excess cobalt oxide is warmed with hydrochloric acid, the cobalt oxide will react with the acid to form cobalt chloride, water, and chlorine gas. The resulting solution may be pink due to the presence of cobalt ions, which are often a characteristic color of cobalt compounds.
Cobalt does not react with water at room temperature. However, finely powdered cobalt can react with water over time to form cobalt hydroxide and hydrogen gas.
It would appear to be a molecule of cobalt hydroxide.
Cobalt itself does not react with water. However, when submerged in water, cobalt can undergo oxidation reactions which might produce cobalt hydroxide, resembling a blue powder, and hydrogen gas.
No, conglomerate does not react to acid.
Cobalt react with oxygen, sulfur, fluorine, chlorine, carbon, nitrogen etc.
Cobalt form many important alloys with other metals.
CoCO3 (Cobalt II carbonate) would be a weak base.
Plutonium easily react with nitric acid.
The name of the acid is carbonic acid (H2CO3).
Germanium does not react with hydrochloric acid at room temperature. However, it can react with hydrochloric acid when heated, forming germanium chloride.
Gold react with aqua regia not with hydrochloric acid.
