Assertion ammonia solution is an alkali
WebJun 8, 2024 · The production of these ammonia electrolytes was, however, only possible with considerable technical effort and under many safety precautions. The biggest problem is that pure alkali metals in air react immediately with oxygen and water, which might not lead to an explosion but at least to a metal fire that can be several thousand degrees hot. WebSolutions of alkali metals in liquid ammonia are good reducing agents,because they contain free or solvated electrons The reducing character is due to the presence of solvated unpaired electrons, e.g. O2 +2e− O22− So Both Assertion and Reason are correct and Reason is the correct explanation for Assertion. Hence option A is correct.

WebThese solution of metals in liquid ammonia conduct electricity better than any salt in any liquid. Here, the conductions is mainly due to the presence of solvated electrons. This dilute solution of alkali metal in liquid ammonia is paramagnetic in nature due to the presence of the unpaired electrons. Hence option (c) is a wrong statement. Theory WebSolution Verified by Toppr Dry ammonia does not liberate any ions like OH − as it is not in contact with water, thereby has no action on litmus paper. Ammonia solution in water turns red litmus blue as it forms Ammonium ion ( NH 4+) and hydroxyl ion ( OH − ). NH 3+H 2O→NH 4++OH − Thus, here ammonia act as a base by liberating OH − ion.
WebAug 21, 2024 · The reaction between persulfate ions (peroxodisulfate ions), S 2 O 82-, and iodide ions in solution can be catalyzed using either iron (II) or iron (III) ions. The overall equation for the reaction is: (2) S 2 O 8 2 − + 2 I − → 2 S O 4 2 − + I 2. For the sake of argument, we'll take the catalyst to be iron (II) ions.
