An unknown salt consists of two types of cations and one type of anion
An unknown salt consists of two types of cations and one type of anion. The possible anions include chloride, Cl-, carbonate, CO32-, sulfate, SO42-. The possible cations include Group 1A cations, K+ and Na+, and Group 2A cations, Ca2+ and Sr2+.a) After dissolving the unknown in 20 mL of DI water, you add 0.5 mL of 0.05 M AgNO3 and observe a precipitate. What are the possible precipitates that are formed? Write the net ionic equations for the reactions. b) When...

To determine the salt formed during a neutralization reaction, combine the anion formed by the dissociation of the acid and the cation formed by the dissociation of the base in a ratio that results in a neutral, ionic compound. For example, if you have a cation with a 1+ charge and an anion with a 2- charge, you will need two cations to balance the charge. [(1+ charge on cation)(2)]+[2 - charge on anion)(1)] = (+2) + (-2) = 0...

5. An unknown salt consists of two types of cations and one type of anion. The possible an- ions include chloride, CI", carbonate, CO,2-, sulfate, SO 2-. The possible cations include Group 1A cations, K* and Na*, and Group 2A cations, Ca2+ and Sr2+. c) To identify the two cations in your unknown, you do a flame test, and to confirm the identity, you use precipitation reactions. By adding H,So, to your unknown, you observe no precipitate. What can you...

present
I followed procedure 33 and adding the H2SO4 it had a brown
bubbly reaction and heating it up produced a brown gas.
