Rubidium reacts violently with water to create Rubidium Hydroxide and hydrogen gas. The gas may ignite with the heat of the reaction. The Rubidium Hydroxide remains in solution in the water, and is very strongly alkaline - i.e. it is a base.

Is RbOH a strong base or acid?
RbOH ( Rubidium hydroxide) is a strong alkali. An Alkali is a soluble base.
What is the general form for the simplest type of acid base reaction?
Acid + base salt + water
What is rubidium hydroxide plus hydrofluoric acid?
An acid
6 What happens when an acid is dissolved in water?
it is still acid but weaker because the water-acid base ratio grows depending on how much water or acid base there is You need water to make acid (e.g. Hydrogen Chloride itself is not acid, it is an acid base, but when dissolved in water it is a very strong acid)
Is Salt formed when an acid or a base react chemically?
Yes. An acid-base reaction forms a salt and water. acid+ + base− = salt + water
Is RbOH a strong base or acid?
RbOH ( Rubidium hydroxide) is a strong alkali. An Alkali is a soluble base.
Is the chemical RbOH an acid or base?
Rubidium Hydroxide (RbOH) is a weak base.
What is formed when an acid and a base is mixed?
when an acid and a base combine, salt and water are formed. This process of reaction of an acid and base is called neutralisation.
Explains water's role in acid-base reactions?
water is responsible for ionization of acid and base, without water the terms acid and base are meaningless.
Is Rb3BO3 an actual compound and if so is it soluble?
It is the Rubidium salt of boric acid and is soluble in water.
What is the general form for the simplest type of acid base reaction?
Acid + base salt + water
What is rubidium hydroxide plus hydrofluoric acid?
An acid

What reactive rubidium?
it is a soft metal that reacts with water (and acid) look on left side of periodic table
Is Salt formed when an acid or a base react chemically?
Yes. An acid-base reaction forms a salt and water. acid+ + base− = salt + water
A reaction of an acid and base will produce water and what?
An acid and a base react to form water and a salt
What is an acid neutralized by?
An Acid is neutralised by a Base , Alkali or Carboinate. Remember the general equations. Acid + Alkali = Salt + Water Acid + Base = Salt + Water Acid + Carbonate = Salt + Water + Carbon dioxide. NB An Alkali is a soluble Base.
