Question
The amount of dissolved ions and the unit equivalent The amount of dissolved ions in a solution is expressed using the unit equivalent (Eq) of the ion equivalent of an on relates the charge present on the ion to the number solution. For example, one mole of Na^+ ions will have one equivalent of charge because the charge on a sodium ion is 1+. However, a Ba^2+ ion we have two equivalents ion is 2+. A sample solution containing sulfate ions (SO^2-_4) was analyzed and was found to contain 3 mol of sulfate ions (SO^2-_4). Calculate the equivalent of sulfate ions (SO^2-_4)present in the solution Express your answer numerically.Explanation / Answer
moles = mass / molar mass
Equivalent = mass /equivalent mass
= mass / (molar mass / charge )
= moles x charge
= 3 x 2
= 6
equivalent of sulfate ions = 6
