An alkali is a base in an aqueous solution. It is also a proton acceptor, that is it readily gains H+ ions. Examples of alkalis include NaOH (Sodium Hydroxide), NH3(Ammonia) and KOH (Potassium Hydroxide). Anything that disassociates in solution to make a positive ion plus an OH- ion can be classed as an alkali.
Examples of alkali metals are found in Group 1A (aka Group 1) of the Periodic Table (excluding hydrogen if hydrogen is found listed under Group 1A/Group1 on your version of the periodic table).
Therefore: Li, Na, K, Rb, Cs and Fr are examples of alkali metals.
I can tell you to pick up a chemistry book or better yet a periodic table.
reply: and i can tell you to shhh
Washing soda, sodium carbonate, Na2CO3
Caustic soda, sodium hydroxide, NaOH
Quick lime calcium oxide, CaO
An example of an alkali is Pottasium
potassium hydroxide, KOH
An example of alkali in the house could be a normal 9V battery or toothpaste.
Alkali's neutralise acids. For example, toothpaste is an alkali that neutralises acid in the mouth.
All types of strong alkali do not dissolve well in water. Magnesium hydroxide can be given as an example for an insoluble strong alkali.
Alkali does not Stand for anything its a name given to those bases that dissolve in water. For example NaOH is a BASE that can dissolve in water so its an alkali another important thing is that all Alkali's are bases but all bases are NOT alkali's.
Example 1: Acid - Hydrochloric acid - HCl Alkali - Sodium Hydroxide - NaOH Acid + Alkali -> Salt + Water HCl + NaOH -> NaCl + H2O Example 2: Acid - Hydrochloric acid - HCl Alkali - Magnesium Hydroxide - Mg(OH)2 Acid + Alkali -> Salt + Water 2HCl + Mg(OH)2 -> MgCl2 + 2H2O
An example of an alkali is Sodium Hydroxide (NaOH)

Sodium is an alkali metal.
Sodium is an alkali metal.

All alkali metals exist in nature as compounds.

Alkali metals are lithium, sodium, potassium, rubidium, caesium and francium.They are the metals with the higher chemical reactivity.
Example 1: Acid - Hydrochloric acid - HCl Alkali - Sodium Hydroxide - NaOH Acid + Alkali -> Salt + Water HCl + NaOH -> NaCl + H2O Example 2: Acid - Hydrochloric acid - HCl Alkali - Magnesium Hydroxide - Mg(OH)2 Acid + Alkali -> Salt + Water 2HCl + Mg(OH)2 -> MgCl2 + 2H2O
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
