Use the pH Scale/Table and do a little research of your own to fill in the first, second, fourth, and fifth columns of the chart below [H ] (mol/L). (Examples are provided).

Relationship between the [H ], the [OH-], and pH

Acidity/Basicity

(Indicate areas of strong acids, strong bases, weak acids, weak bases and neutrality) [H ]

(mol/L) pH Aqueous system

(example solution)

fill in

two more acids,

one neutral

two or three bases [OH-]

(mol/L)

Neutrality

1 x 10-1

  1. 0                           1 M hydrochloric acid 1 x 10^0

    1                           1 M hydrochloric acid 1 x 10^-1    HCl

    2                           1 M hydrochloric acid 1 x 10^-2    H2SO4

    --------------------------------------... strong acids

    3                           1 M hydrochloric acid 1 x 10^-3

    4                           1 M hydrochloric acid 1 x 10^-4

    5                           1 M hydrochloric acid 1 x 10^-5

    --------------------------------------... very strong acids

    6                           1 M hydrochloric acid 1 x 10^-6 e.g. ethanoic acid

    --------------------------------------... very weak acids

    7 neutral-----water

    You can see there us a pattern in the molrity of H ions,

    Higher you go higher the basicity, higher the chances of being alkaline.

    Hope this helps, but can you not ask other people to do your homework? This is clearly a school assignment, besides these things are available on the internet.
