Identify the major ionic species present in an aqueous solution of nh4clo4.

The major ionic species present in an aqueous solution of NH4ClO4 are NH4^+ and  ClO4^-.

If we dissolve NH4ClO4 in water, the equation will look like this;

NH4ClO4(aq) > NH4^+(aq) + ClO4^-(aq)

Recall that when we dissolve an ionic compound in water, the ions that are present in the substance becomes the major ionic species present in an aqueous solution.

Hence, when we dissolve NH4ClO4 in water, NH4^+ and ClO4^- are present in solution as the major ionic species in solution.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
