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 : [tex]NH_4Br[/tex] : acidic as it is formed from the combination of strong acid HBr and weak base [tex]NH_4OH[/tex]
potassium cyanide :[tex]KCN[/tex]: basic, as it is formed from the combination of weak acid HCN and strong base KOH
calcium nitrate: [tex]Ca(NO_3)_2[/tex] : neutral, as it is formed from the combination of strong acid and strong base.
calcium hypochlorite : [tex]Ca(ClO)_2[/tex] : basic, as it is formed from the combination of weak acid [tex]HOCl[/tex] and strong base [tex]Ca(OH)_2[/tex]
