1. Solid A and liquid B were analyzed. Solid A was ammonium bromide. Tests were done on each substance. Test on solid A Complete the expected observations Solid A was dissolved in water to form solution A. Solution A was divided in to four approximately equal portions in four test-tubes. a. To the first portion of solution A, approximately 2cm³of aqueous ammonia was added Observations b. To the second portion of the A, approximately 2cm³ of aqueous, sodium hydroxide was added. The mixture formed was warmed. A gas was given off. 1. The gas given off was tested with damp red litmus paper. Obervations. ii. Identify the gas given off. c. To the third portion of solid A, approximately 1cm³ of dilute nitric acid followed by a few drops of aqueous silver nitrate was added. Obervation_ d. To the four portion of solid A, approximately 1cm of aqueous chlorine was added. Obervations​
