Is the solution of ammonium chloride acidic or basic?

Answer 1

Assuming that the solvent is water, then NH4Cl (aq) is weakly acidic. This is because the Ammonium ion is Bronstead-Lowry acidic: it can donate H+ to give a neutral NH3 molecule. NH4(+) + H2O <----> NH3 + H20 + H(+) (Reversible reaction) If NH4Cl (ammonium chloride) is added to the solution, this will increase the concentration of NH4+. Since there is greater concentration of NH4(+), more H(+) ions will be released into solution, decreasing the pH, increasing the pOH, and thus making the solution acidic. Therefore a solution of any ammonium salt in water, not just ammonium chloride, is weakly acidic.

Answer 2

Basic. Like ammonia, amines are able to accept an H+ ion from water, forming an ammonium ion and a hydroxide ion. Substances that accept H+ ions are (by definition) bases, and the formation of OH- in aqueous solution causes the solution to have a pH above 7, which makes it basic.

Answer 3

Metal oxides are bases. So when dissolved in water they will become a basic solution.

NB Non-metallic oxides form acidic solutions.

e.g. CaO + H2O = Ca(OH)2 an alkaline solution.

e.g. SO2 + H2O = H2SO3 (Sulphurous ACID)

NB. Aluminium oxide is amphoteric it can form an acid or alkali depending on its environmental pH.

Answer 4

The solution of ammonium chloride is acidic. Ammonium chloride dissolves in water to form ammonium ions (NH4+) and chloride ions (Cl-). The ammonium ion is weakly acidic because it can donate a proton to water, resulting in the formation of ammonium hydroxide.

Answer 5

Yes the water become acidic
