Acids and Bases

HideShow resource information

Acids and Bases

- When mixed with water all acids release hydrogen ions. Acids are proton donors.

- When mixed in an aqueous solution bases remove H+ ions. They are proton acceptors

Acids react to form neutral salts

Acids release H+ ions so they can react and be replaced by other ions to form a salt. You get a salt if you react a salt and the hydrogen ion is replaced with an ammonium ion or a metal ions.

Acids and Bases

Reactions - acids and bases

-Acids react with bases to neutralise them. 

-Metal oxides, metal hydroxides, and ammonia are common bases (an alkali is a base that dissolves in water)

-Alkalis release OH- ions that accept the H+ ions to produce water 

- Base + acid ---> salt + water

Reactions - Metal

- Metal + acid ---> Salt + hydrogen

Reactions - Metal carbonates

- Metal carbonate + acid ---> salt + water + carbon dioxide
