Oven cleaners are generally basic because they contain chemical species that act as bases by increasing the concentration of the hydroxide ion, OH- , in the substance. Although the formulations vary, some oven cleaners contain ammonia, which is basic by the following reaction: NH3 + H2O ---> NH4+ + OH-
The most commonly used measure of concentration for an aqueous solution is molarity, which is the number of moles of solute per liter of solution.
Atoms whose outer electron shells contain eight electrons tend to be stable and do not easily form ionic bonds in aqueous solutions. This is because they have reached the stable configuration known as the octet rule. In most cases, atoms that form ionic bonds have outer electron shells that are not fully filled with eight electrons.
The oxide that would exhibit the most acidic character in aqueous solution is likely to be the one with the highest oxidation state of the central atom.
Substances that conduct electricity in an aqueous solution include salts, acids, and bases. These substances dissociate into ions when dissolved in water, allowing them to conduct electric current.
Colourless solution. most coloured solutions contain transition metal ions
Alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known for being bases that dissolve in water. (Most common form is hydroxide.)A base is most commonly thought of as an aqueous substance that can accept H+ ions.A soluble base is also often referred to as an alkali if hydroxide ions (OH−) are involved."All alkali are bases but not all bases are alkali"

Water?
It is most commonly in liquid form - as an aqueous solution.
