Indicate whether each of the following compounds will gave an acidic, basic or neutral solution when dissolved in water. Clear A
allsm [11]

Answer: ammonium bromide : acidic : The pH will be less than 7.

potassium cyanide : basic :The pH will be more than 7.

calcium nitrate: neutral : The pH will be approximately equal to 7.

calcium hypochlorite : basic :The pH will be more than 7.

Explanation:

pH is defined as the negative logarithm of hydrogen ion concentration. The scale ranges from 0 to 14.

When a solution is acidic, it will show a pH in the range of 0 - 6.9. When a solution is basic, it will show a pH in the range of 7.1 - 14. When a solution is neutral, it will show a pH of 7.

ammonium bromide : NH_4Br : acidic as it is formed from the combination of strong acid HBr and weak base NH_4OH

potassium cyanide :KCN:  basic, as it is formed from the combination of weak acid HCN and strong base KOH

calcium nitrate: Ca(NO_3)_2 : neutral, as it is formed from the combination of strong acid and strong base.

calcium hypochlorite :  Ca(ClO)_2 : basic, as it is formed from the combination of weak acid HOCl and strong base Ca(OH)_2
