- Write the equations for the dissocation of the following in aqueous solution:Na2S:[(NH4)2]CO3:KHSO3:Suppose you made a mistake in Ag group analysis, If instead of 6M HCl you used 6M H2SO4 what will you observe? Can you continue from that point on to separate the cations ?How?Explainexplain anharmonicity.
- Which is a weaker acceptor (analogous to weaker acid)? In, CuWhich is a weaker donor (analogous to weaker base)? As, MnPart II. Arrange the following compounds in order of increasing basicity. Part III. Determine if the oxide is acidic or basic.What color do you expect for cresol purple at pH 1.0, 2.0, and 3.0?
- Calculate the equilibrium constant, Kc, of the reaction: HCO3-(aq) + HCO3-(aq) ↔ H2CO3(aq) + CO32- , Kc = ? Based on your result, do you expect this reaction to occur in the left-to-right direction?25. Explain, with balanced ionic equations, why (a) Culz dissolves in ammonia solution, ( Make sure to give conclusion to explain why; All equations have to balance.) (b) AgBr dissolves in NaCN solution, and (c) HgCl2 dissolves in KCI solution.Like any equilibrium constant, Kᵥᵥ changes with tempera-ture. (a) Given that autoionization is endothermic, how does Kᵥᵥ change with rising T? Explain with a reaction that includes heatas reactant or product. (b) In many medical applications, the value of Kᵥᵥ at 37°C (body temperature) may be more appropri-ate than the value at 25°C, 1.0X10⁻¹⁴. The pH of pure water at 37°C is 6.80. Calculate Kᵥᵥ, pOH, and [OH] at this temperature.
