Health Sciences homework help. 4. Identify which of the possible unknowns for this experiment would give the following behavior.× A clear, colorless solution of the unknown tested acidic to indicator paper. × Testing with indicator paper indicate that the solution had an acidic pH. × Nothing was observed when KOH was added to the first test tube. × Nothing was observed when AgNO3(aq) was added to the second test tube. × A white precipitate formed when BaCl2(aq) was added to the third test tube. (Note that under the conditions used in our lab experiment, Ag2SO4 does not form a precipitate.) come up with a balanced molecular equation including states of matter for the reaction observed between this compound and BaCl2.5. Identify which of the possible unknowns for this experiment would give the following behavior.× A clear, blue solution of the unknown tested acidic to indicator paper. × There was no reaction when this unknown was tested with either AgNO3(aq), dilute H2SO4, or BaCl2(aq). × A black precipitate was formed when the unknown was treated with Na2S(aq).× A pale blue precipitate was formed when the unknown was treated with KOH(aq). come up with a a balanced molecular equation including states of matter for the reactions observed with Na2S and KOH.6. Which reagent available in this experiment will distinguish between a soluble Cl- salt solution and a soluble NO3- salt solution? Explain your reasoning.
