Correct solubility equation for the salt A2B3 is
A2B3(s) <==> 2A+3(aq) + 3B-2(aq)
so option 5 is correct.
Add Answer to:
Consider a salt with the formula A2B3, where A denotes the cation and B denotes the...

Consider a hypothetical salt of low solubility, "MX", where M+ is a metal cation and X- is a non-metal anion. A voltaic cell was set up with a cathode containing metal "M" immersed in a solution containing M+ at a concentration of 1.00 mol L-1. The anode consisted of metal "M" immersed in a saturated solution of "MX". The measured cell voltage was 0.251 V. What is the Ksp of "MX" at 25°C ?

Molten salts When electricity is applied to a molten binary salt, the cation will be reduced and the anion will be oxidized. The electrolysis of CaBrz (), for example, produces Ca(s) at the cathode (from the reduction of Ca2+) and Br2(1) at the anode (from the oxidation of Br"). If more than one cation is present, only the one with highest reduction potential will be reduced. Similarly, if more than one anion is present, only the one with the highest...

I need to name an ionic compound containing a transition metal cation and a halogen anion. Below are the rules I should follow to write the correct name for such compound, but one of the options is incorrect: identify and select it. Select one: a. Identify the metal and write its name first b. Use the periodic table to work out the charge (oxidation number) on the transition metal according to the group in the periodic table c. From the...

Consider the following logical expressions where A + B denotes A logical OR B, AB denotes A logical AND B, and ¯ A denotes inverse of A. Derive at least one additive (to be added by logical OR operation) term (excluding obvious 0, 1, A ¯ A or similar) which will not affect the result of the expression. For example, adding (by means of logical OR) term B C D to AB C+ ¯AB D does not change the result,...

Consider the following salt solutions: (i) NH4Cl – NH+ + C- Notice that as a salt, NH,Cl dissociates completely in solution. So, what are the parents of this salt? The cation, NH, in this case, is from the base obtained by adding enough OHto balance the positive charge(s) on the cation; Viz, NH,OH. Similarly, the anion, Cl. comes from the acid. So the parent acid can be obtained by adding enough Hi to neutralize the charge...
