Question $1$: Magnesium borate is slightly soluble in water:MgB$2$O$4=$ Mg$2++2$BO$2-$a$)$ Assume that a small amount of magnesium borate is added to $1$ kg water. If the equilibrium concentration of Mg$2+$ is found to be $2\mathrm{.}965$x$10-2$ mol$/$kg$,$ determine Ka:i$)$ Use the Debye$-$H$$ckel equation.ii$)$ Use the Davies equation b$)$ Determine the equilibrium concentration of Mg$2+,$i$)$ If $0\mathrm{.}3$ mole NaCl is added to the solution in part $($a$)$ii$)$ If $5$ mole NaCl is added to the solution in part $($a
