Bath salt is typically composed of the items listed below.Identify each item as being acidic,basic,or neutral when dissolved in water.If a particular ingrediant does make an acidic or basic solution,describe how this occurs.

NaCl, Na2SO4, NaHCO3, sodium citrate, CaCl2

Expert Solution

NaCl - neutral when dissolved in water.

NaCl is a salt of strong acidHCL and a strong base NaOH . thus does not undergo hydrolysis.

Thus its aquous solution is neutral.

Na2SO4 - its aqueous solution is also neutral as this is made up of a strong acid H2SO4 and strong base NaOH.

BOth the cation and anion do not hydrolyse in water , thus the solutionis neutral.

NaHCO3 - basic in aqueous solution.

It is made from a strong base NaOH and weak acid H2CO3 .

Thus the anion HCO3- undergoes hydrolysis increasing the [OH-] in water to makeit basic.

HCO3- + H2O ---------> H2CO3 + OH-

sodium citrate

Basic in water solutions as it is a salt of weak acid ctric acid and strong base NaoH

the anion citrate undergoes hydrolysis to gie weak acid citric acid and OH- ions. thus basic.

citrate + h2O --------------> citric acid + OH-

CaCl2

acidic in water solution

is a salt of weak base Ca(OH)2 and strong acid HCl.

Thus the cation Ca+2 undergoes hydrolysis to give weak base and H+ ions.

Ca+2 + 2H2O ----------> Ca(OH)2 + 2H+

Thus the solution is acidic.
