Answer 2

acid

Question 3

definition of a base

Answer 3

proton acceptor

Question 4

proton acceptor

Answer 4

base

Question 5

definition of an alkali

Answer 5

water soluble base that release OH- ions in aqueous solution

Question 6

water soluble base that release OH- ions in aqueous solution

Answer 6

alkali

Question 7

NH3 (aq) + HNO3 (aq) -> NH4NO3 (aq) what are the equations to get to NH4NO3?

Answer 7

NH3 + H2O <-> NH4OH NH4OH + HNO3 -> NH4NO3 + H2O

Question 8

definition of a salt

Answer 8

a compound formed when the H+ ions from an acid are replaced by metal ions or ammonium ions

Question 9

a compound formed when the H+ ions from an acid are replaced by metal ions or ammonium ions

Answer 9

a salt

Question 10

difference between strong acids/alkalis and weak acids/alkalis

Answer 10

strong = ionise fully in aqueous solution weak = ionise partially in aqueous solution
