34. Of the following ions, the solution that produces an acidic pH is:
a.ClO2 -
b.NH4 +
c.NO3-
d.Br-
ClO2-, NO3-, Br- are all having negative charge which can be
donated.
So, all of them are Lewis base and hence they will produce basic
pH.
On the other hand, NH4+ has H+ which can be donated and hence NH4+ act as acid.
So, NH4+ will produce acidic pH
Answer: b

2 points 11 My Notes Acidity of solution is determined by the concentration C of hydrogen ions in the solution (measured in moles per liter of solution). Chemists use the negative of the logarithm the following formula. of the concentration of hydrogen ions to define the pH scale, as shown pH log (C) Lower pH values indicate a more acidic solution. (a) Normal rain has a pH value of 5.6. Rain in the eastern United States often has a pH...
18. Acidity of a solution is determined by the concentration Hof hydrogen ions in the solution (measured in moles per liter of solution). Chemists use the negative of the logarithm of the concentration of hydrogen ions to define the pH scale. pH = -log H Solution A has a pH value of 5.6 and solution B has a pH value of 2.7. Compare the acidity of the two solutions. a) Solution A is more acidic by a factor of 2.07...
