Question

What is the formula for rubidium chloride?

Answer 1

Hint: Rubidium chloride is an alkali metal halide with the elements rubidium and chlorine. Rubidium is a chemical element with the symbol ‘Ru’ which is included in the alkali metal group. And the atomic number of rubidium is \[37\]. We also know that the chlorine is a chemical element with the symbol ‘Cl’ having the atomic number \[17\].

Complete step by step answer:
Rubidium chloride is an inorganic compound and it's scientifically established that the ratio of rubidium and chlorine is \[1:1\]. And it can be prepared by the reaction of rubidium hydroxide with hydrochloric acid by recrystallization. The reaction can be written as,
\[RbOH + HCl \to RbCl + {H_2}O\]
As we know that the rubidium chloride is a white crystalline powder that is hygroscopic in nature and is primarily used in laboratories. We have to remember that in medicine it is also used as an antidepressant and a biomarker. Rubidium chloride is diatomic in the gas phase with bond length, \[2.7868{A^o}\]. And the bond length is increased for cubic rubidium chloride.
Hence, the formula of Rubidium Chloride is $RbCl$

Note: The formula for rubidium chloride is $RbCl$ having the ratio of rubidium and chlorine is equal to \[1:1\]. And this rubidium chloride is mainly used as a gasoline additive and has the highest antidepressant effects. Depending on the conditions, the solid state of rubidium chloride has one of three arrangements (polymorph). Rubidium chloride reacts with sulfuric acid to give rubidium hydrogen sulfate.
