Rubidium (Rb, Z=37). Rubidium is a soft, white metal; it is similar to sodium and potassium in its reaction with water, but the reaction is even more violently exothermic. Its name is derived from the Latin word for deep red (ruby), rubidius. It is found in the Earth's crust at a concentration of 90 ppm, making it the 22nd most abundant element.

First, write the equation for the dissolving process, and examine each ion formed to determine whether the salt is an acidic, basic, or neutral salt. KCN(s) --> K + (aq) + CN-(aq) K + is a neutral ion and CN-is a basic ion. KCN is a basic salt. Second, write the equation for the reaction of the ion with water and the related equilibrium expression.

Aim: Salt reabsorption across the apical membrane of cells in the thick ascending limb (TAL) of Henle is primarily mediated by the bumetanide-sensitive Na(+)/K(+)/2Cl(-) cotransporter NKCC2. Three full-length splice variants of NKCC2 (NKCC2B, NKCC2A and NKCC2F) have been described. The NKCC2 isoforms have specific localizations and transport characteristics, as assessed for rabbit, rat and mouse.

Rubidium metal reacts very rapidly with water to form a colourless solution of rubidium hydroxide (RbOH) and hydrogen gas (H 2 ). The resulting solution is basic because of the dissolved hydroxide. The reaction is very exothermic. The reaction is so fast that if the reaction is carried out in a glass vessel, the glass container may well shatter.
