You cannot balance these two compounds (barium chloride and sodium sulfate, respectively) because they are not in a chemical reaction. However, if you put them in an equation (also known as a reaction), it can be balanced as follows:
BaCl2 => Ba++ + 2Cl2+
Na2SO4 => 2Na+ + SO4-- (SO4 is a polyatomic ion known as sulfate)
Both equations represent what will happen to either of these chemical compounds when they dissolve in water. Both of these ionic compounds are water soluble, and will "break up" into ions in water.
BaSO4 + Na2Cl2
bacl2
Test for the anions,according to your word,i think you got the salts,so, use these reagents HCL,BACL2,Adding bacl2 and Hcl to Naso4-white ppt observed in soluble,but barium chloride will give no ppt...so probem solved

The chemical formula of sodium sulfate is Na2SO4. The chemical formula of barium chloride is BaCl2. BaCl2 + Na2SO4-----------BaSO4 + 2 NaCl BaSO4 is a white, practically insoluble in water precipitate; this property is important in gravimetric analysis.
Na2SO4 (aq) + BaCl2 (aq) ---> 2 NaCl (aq) + BaSO4 (s)
Balanced equation first. BaCl2 + Na2SO4 -> 2NaCl + BaSO4 22.6 ml BaCl2 = 0.0226 liters 54.6 ml Na2SO4 = 0.0546 liters 0.160 M BaCl2 = moles BaCl2/0.0226 liters = 0.00362 moles BaCl2 0.055 M Na2SO4 = moles Na2SO4/0.0546 liters = 0.0030 moles Na2SO4 The ratio of BaCl2 to Na2SO4 is one to one, so either mole count wull drive this reaction. Use 0.0003 moles Na2SO4 0.0030 moles Na2SO4 (1 mole BaSO4/1 mole Na2SO4)(233.37 grams/1 mole BaSO4) = 0.700 grams of BaCO4 produced

The chemical formula of sodium sulfate is Na2SO4. The chemical formula of barium chloride is BaCl2. BaCl2 + Na2SO4-----------BaSO4 + 2 NaCl BaSO4 is a white, practically insoluble in water precipitate; this property is important in gravimetric analysis.
BaCl2 + K2SO4 --> BaSO4 + 2KCl

Na2SO4 (aq) + BaCl2 (aq) ---> 2 NaCl (aq) + BaSO4 (s)
BaCl2(aq) + Na2SO4 (aq) ------> BaSO4(s) + 2NaCl(aq)
Assuming that the intended reaction is BaCl2 (aq) + Na2SO4 (aq) => 2 NaCl (aq) + BaSO4 (s), this is not a redox reaction. Instead it is an ion interchange reaction, driven by the fact that BaSO4 is much less soluble in water than any of the other ions pairs barium chloride, sodium chloride, and sodium sulfate.
The balanced equation for sodium sulfate (Na2SO4) plus barium chloride (BaCl2) yielding barium sulfate (BaSO4) and sodium chloride (NaCl) is: Na2SO4 + BaCl2 -> BaSO4 + 2NaCl
This equation is BaCl2 (aq) + Na2SO4 (aq) -> 2 NaCl (aq) + BaSO4 (s).
