Based on the following chemical reaction, determine if the following substance (H_2Cr_2O_7) is an acid or a base. a base an acid neutral compound an amphoteric compound none of the above If a soil has a pH of 4.7. what is the [OH] concentration of the soil solution? 2 times 10^-5M B 5 times 10^-10M 1 0 times 10^-14 1.0 times 10^-11 1.0 times 10^-9

Solution

24. B

The substance which release H⁺ in aqueous solution are called acids.

We can see in above that H2C2O4 release H+ in water so it acts as acid.
