Wale the charges on negative and posiltive lons ithay are formed Express your answer as a complete chemical equation Including all phases. Do not Include water in your answer Hints nl. or (a0 for sold, liquid, or gas Use (ng) to e amount of dissolved ions in a solution is expressed using he unit equivalent (Ea) of the lon A unit equilvalent of an ion relates the charge present on the ion to the mumber of moles of the lons present in the solution For of charge because the charge on a sodum ion is 1+ However,Ba lon will have twe equlvalents of charge because the charge on a barium kon is 2 rt c sample sokution containing alite ons (SO, )was analyzed and was found to contain 5 mol of wuate ions (0.) Calculate the equivalent of sulate ions (S0,2 )present in the solution Express your answer numerically Hints

Explanation / Answer

Equivalent mass of an acid is calculated as= Molecular mass of acid / No. of displacable H- (basicity).

For H2SO4, the basicity is 2. hence molar mass is twice the equiavalent mass.

As it was a solution of sulphate ions we can safely say that 1 mole of sulphate ions = 2 equivalent of sulphate ions.

Hence 5 moles of sulphate (sulfate) ions have 10 equivalent of Sulphate ions in the solution.
