Is rubidium an acid or base?
Rubidium acetate is the alkali metal salt of a weak acid…..
What happens when rubidium is put in water?
Rubidium: Rubidium sinks because it is less dense than water. It reacts violently and immediately, with everything leaving the container. Rubidium hydroxide solution and hydrogen are formed.
Is rubidium acidic or alkaline?
Rubidium is the first alkali metal in the group to have a density higher than water, so it sinks, unlike the metals above it in the group. Rubidium has a standard atomic weight of 85.4678.
What is the pH of rubidium?
The pH of a 0.0150 M aqueous solution of rubidium hydroxide (RbOH) is D. 12.2.
Is rubidium neutral?
Rubidium atoms have 37 electrons and the shell structure is 2.8. The ground state electronic configuration of neutral rubidium is [Kr]. 5s1 and the term symbol of rubidium is 2S1/2.
What group is rubidium?
Group 1

Is rubidium hydroxide acidic?
Rubidium Hydroxide is a base. When Rubidium Hydroxide is dissolved in water it is an alkali. Rubidium Hydroxide reacts with acids to produce a Rubidium salt: Hydrochloric Acid + Rubidium Hydroxide → Rubidium Chloride + Water.

What is the chemical formula for rubidium and water?
Chemical Formula: RbOH Formula Equation: 2 Rb (s) + 2 H 2 O (l) → 2 RbOH (aq) + H 2 (g) Word Equation: Rubidium + Water → Rubidium hydroxide + Hydrogen Reaction: It reacts very violently because the reaction is supremely quick which results in an explosion.
What happens when rubidium is mixed with water?
Word Equation: Rubidium + Water → Rubidium hydroxide + Hydrogen Reaction: It reacts very violently because the reaction is supremely quick which results in an explosion. As it reacts it releases heat (exothermic).
Is there a reaction between an acid and a base?
There is a reaction between an acid and a base when a compound containing hydrated aluminium ions are added to water. (1.) How can this be shown experimentally? (2.) Write the formula of the reacting acid.
Which is not an acid in a water molecule?
Those that are not acids are metal cations with a +1 charge (M+), and a few of the larger M2+ions (Ba2+, Sr2+, Ca2+). Other hydrated metal cations behave as acids in water due to the loss of one of the H+ions from water molecules attached to the cation.
