How many moles of Ba3(PO4)2 will be formed by the reaction of 5 moles of BaCl2 and 3 moles of Na3(PO4).
The reaction between BaCl2 and Na3PO4 is:
3BaCl2 + 2Na3PO4 → Ba3(PO4)2 + 6NaCl
The balanced equation shows that 3 moles of BaCl2 react with 2 moles of Na3PO4 to produce 1 mole of Ba3(PO4)2.
Now, using the mole ratio from the equation:
The number of moles of Ba3(PO4)2 formed is 5 moles.
MX is a sparingly soluble salt that follows the given solubility equilibrium at 298 K.
MX(s) $\rightleftharpoons M^{+(aq) }+ X^{-}(aq)$; $K_{sp} = 10^{-10}$
If the standard reduction potential for $M^{+}(aq) + e^{-} \rightarrow M(s)$ is $(E^{\circ}_{M^{+}/M}) = 0.79$ V, then the value of the standard reduction potential for the metal/metal insoluble salt electrode $E^{\circ}_{X^{-}/MX(s)/M}$ is ____________ mV. (nearest integer)
[Given : $\frac{2.303 RT}{F} = 0.059$ V]
