Copper doesn't react wih alkalis.
Bases and Alkalis are the opposites of acids. Alkalis are bases dissolved in water. When combined in the equal quantities, they neutralise each other.
Some metals react with alkalis; for example the reaction of aluminium with sodium hydroxide is:2 Al + 2 NaOH + 2 H2O = 2 NaAlO2 + 3 H2
Acids have a pH under 7, alkalis have a pH bigger than 7.
The most common is Litmus. Litmus is extracted from various Lichens and is a good indicator of both acids and alkalis. Some naturally occurring substances indicate only acids or alkalis such as cochineal and curcumin. The common litmus paper is impregnated with the dye extract of the Lichen to act as an acidity or alkalinity indicator. All PH (acidity and alkilinity) measuring devices work based upon whether they accept or donate protons and as such are infact themselves acids or bases. For greater accuracy other dyes (other than the reactive element) are added to the PH detector which can be chemically engineered to give visible changes in colour at every step on the PH scale.
All alkalis are soluble in water.
Yes, all alkalis contain oxygen and hydrogen.
Yes all alkalis have an OH- group, however this is not true for bases.
COMMON alkalis found at home:cleaning productsbathroom cleanerssoapi think baking soda anddishwasher detergentshope it helps
No- hydrochloric acid is an acid and is the opposite of an alkali so no alkalis contain it
Yes, they do.
Calcium Hydroxide & Ammonia Solution & Sodium Hydroxide. Are the Common Alkalis you find in a Lab
don't you mean dangerous
They all contain acid and bases
No, many alkalis (bases) do not. These include potassium carbonate (Na2CO3), sodium hypochlorite (NaClO), and calcium oxide (CaO).
maybe
sodium hydroxide ammonia
