—evaporate 5 ml of hydrochloric acid on a water bath to dryness, and add 2 ml of dilute acetic acid and water to the residue to make 50 ml. perform the test using this solution as the test solution. pre- pare the control solution as follons: to 3.0 ml of standard lead solution ...
From the solution of zinc chloride,hydrogen gas evolves as bubbles. Thus, when dilute hydrochloric acid is added to a test tube containing granulated zinc we can see that a colourless and odourless gas evolves with bubbles.

In carbonate solutions, O2 reduction currents were suppressed by up to an order of magnitude (compared with those in perchlorate) and copious amounts of peroxide were released to solution. The theory developed by Presnov and Trunov for O2 reduction on transition metal oxides with p-type semi...
3429. [Class 1 (ii)] Carbonate or bicarbonate solutions of usable concentration are obtained starting from dilute alkaline solutions containing alkali or ammonium ions by the combination of steps comprising contacting the dilute solution with a cation exchange material having exchangeable hydrogen ions ...
