The answer is 20,79 mL (0,021 L).
The chemical reaction between Cu(NO3)2 and Na2SO4 is a double displacement reaction. The products of this reaction are CuSO4 (copper(II) sulfate) and NaNO3 (sodium nitrate).
Any reaction between CaMg(CO3)2 and BaCl2.
This reaction is:Ba(ClO3)2 = BaCl2 + O2
Ba(NO3)2(aq) + Na2SO4(aq) ==> BaSO4(s) + 2NaNO3(aq). The reaction results in the formation of insoluble barium sulfate (BaSO4).
Double-Replacement-Apex
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
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.
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
Na2SO4 (aq) + BaCl2 (aq) ---> 2 NaCl (aq) + BaSO4 (s)
bacl2
NaNO3 + H2SO4
2NaCl + H2SO4 = Na2SO4 + 2HCl
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.
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.
Exchange synthesis reaction
An exchange reaction is defined as a chemical reaction in which two different molecules or pairs of molecules exchange places. So yes, a chemical exchange reaction will result in different molecules trading positions.
