help with lab questions please
The following reaction is an example of a precipitation reaction you have seen in general chemistry. BaCl2 and NazSO4 have an (aq) after them meaning they are soluble in water...hey are IN solution 3. BaCl2 (ag)+ Na SO aq) BaSO4+ + 2NaCI Using the solubility chart given, fill in the parentheses for BaSO, as either aq (soluble in water), or s (precipitates/not soluble in water) Using the solubility chart in Appendix I of this worksheet, fill in the parentheses for NaCl as either aq (soluble in water), or s (precipitates/not soluble in water) a. b. Given the exercise in #3, how might you design an experiment to test that a reaction shown in #2 is occurring in your test tube? 4.Explanation / Answer
3.
a) BaCl2(aq) + Na2So4(aq) ------------- BaSO4(s) + 2 NaCl
b) BaCl2(aq) + Na2So4(aq) ------------- BaSO4(s) + 2 NaCl(aq).
4) what is the question number 2.
