Write the charge balance for an aqueous solution of arsenic acid, H3AsO4, in which the acid can dissociate to H2AsO24 , HAsO24 2, and AsO34 2. Look up the structure of arsenic acid in Appendix G and write the structure of HAsO24 2.

Kindly check the explanation section.

Explanation:

When the Arsenic acid,H3AsO4 is put in water it dissociates to form or give out 1 proton, 2 protons or 3 protons that is 1H^+, 2H^+ and 3H^+. Check the equation showing the dissociation reactions as given below;

H3AsO4 > H^+ + AsO4^-

H3AsO4 > 2H^+ + AsO4^2-

H3AsO4 > 3H^+ + AsO4^3-

Therefore, the total charge balance is given as:

[H^+] =[OH^-] + [ AsO4^-] + 2[ AsO4^2-] + 3[ AsO4^3-].

Kindly note that the [OH^-] is from water.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
