salts

what is producd in a neutralisation reaction between an acid and a base

a salt

when a salt dissolves in water and the compound dissociates completley what does it give?

cations and anions

what is the difference between cations and anions

cations are postively charged while anions are negatively charged

what effect does hydrolysis have on pH of solution

• Strong acid – strong base

• Strong acid – weak base

• Weak acid – strong base

• Weak acid – weak base

how can salt be deemed neutral

as neither Na or Cl react with water so salt is neutral

example of a neutral salt

NaCl

why does only Cl react with water

Cl is a weak conjugate base

why does NH4 react with water when CL DOES NOT

NH4 is the conjugate acid of a weak base

what can yield a neutral salt

equal concentrations of ions

what is an acidic salt

strong acid + weak base

what is a basic salt

weak acid + strong base

what are the two neutral salts

strong acid + strong base

weak acid + weak base

what is an amphiprotic salt

when it can both function as an acid and a base
