Answer 1

(a) Beaker A solution in the figure below contains K ions and NO, ions. Beaker B contains a solution containing NH ions and Br ions. A в (2) NO К* Br NH Solutions from beaker A and B are mixed. Then mixture will contain four types of ions. K*(aq)NO, (aq) NH, (aq) Br (aq) We have to determine whether any combination of cations and anions gives an insoluble salt. As per the rules of solubility, a salt containing K* and Br is soluble in water, and other combinations of NH ions with NO, ions also give a soluble salt Therefore, when solutions from beaker A are mixed with solutions of beaker B, the mixture will contain all four types of ions in the solution

Beaker 1 in the figure shows a solution in which all four types of ions are present in the solution Hence, beaker 1 contains a product of the reaction that occurs when solutions of beakers A and B are mixed

Beaker 2 shows that K+ ions and NH ons are settled at the bottom, and NO, ions and Br-ions are moving in solution. So, beaker 2 does not contain the product of the reaction that forms when solutions from beakers A and B are mixed.

Beaker 3 shows that NH ions and NO, ions are settled at the bottom, and K* and Br ions are moving in solution. So, beaker 3 does not show the product of the reaction as it does not show all 4 types of ions moving in the solution.

Beaker 4 shows that K* ions and Br ions are settled at the bottom, and NH ions and NO, ions are moving in the solution. Beaker 4 does not show all 4 types of ions moving in solution, so it does not contain the product of the reaction between solutions from beakers A and В

Therefore, beaker 1 contains the products of the reaction formed when solutions from beakers A and B are mixed

(b) When solution from beaker A containing K* and NO, ions is mixed with a solution in beaker B containing NH and Br ions, no insoluble salt is formed. K*(aq)NO, (aq) NH, (aq) Br (aq)no reaction

c) No reaction found when solution from beaker A containing K* and NO, ions is mixed with a solution in beaker B containing NH and Br ions. Therefore, we cannot write a net ionic equation
