when acids are mixed with alkalis they become?/
acids react with carbonates to produce?

Answer 1

they become salts

they react with carbonates to produce carbon dioxide

Answer 2

Sorry folks, strictly speaking these answers above are in fact not all correct. The terms "alkali" and "base" do not refer only to hydroxide salts! Thus, "water" is not the only thing that can be produced from the reaction of acid plus either base or alkali. For example, sodium ethoxide would be considered alkali, and the reaction of that with a Bronsted acid yields ethanol (plus a salt, e.g. NaCl if the acid is HCl). Lithium amide (LiNH2) is a base, and the reaction of that with a Bronsted acid yields ammonia (plus a salt, e.g. LiCl if the acid is HCl). So the correct answer really for product of an acid + alkali, or acid + base = conjugate acid of the base plus the conjugate base of the acid (frequently a salt)! A Bronsted acid plus metal indeed typically yields a metal ion + H2 (and indeed there are exceptions) A Bronsted acid + a carbonate salt indeed typically yields carbon dioxide plus water plus a salt

Answer 3

acid reacting with an alkali:
HCl + NaOH ----> H20 + NaCl
They produce a salt because the acid and base neutralize eachother.

A reaction between an acid and a carbonate forms a salt, carbon dioxide and water
eg:
Nitric acid and sodium carbonate ---> sodium nitrate and carbon dioxide and water
2HNO3 + Na2CO3 ---> 2NaNO3 + CO2 + H2O

Answer 4

1. Salts

2. Salts + carbon dioxide

Answer 5

acids react with bases to produce a salt and water
ex:
HCl+NaOH-----> NaCl+H2O


acids react with carbonates to produce a salt , CO2 and H2O
ex:

2HCl + CaCO3 ----> CaCl2 + CO2+H2O
