A 0.47M aqueous solution of butylamine has a ph of 12.13. GIven: pKb NH3=4.75. Combine the solutions and the $\mathrm{pH}$ will settle out somewhere between $1$ and $7,$ because of the common ion effect: $\ce{F-}$ from the $\ce{NH4F}$ inhibits the ionization of $\ce{HF},$ but the solution is still acidic. So the pH is determined by their Ka value. Please consider using proper formatting tools (. - CO32- [H+]=7.22106M c. [H+]=8.05107Md. HCN+NaOHNaCN+H2O Cotton candy is a type of confectionery that is made from sugar. But they can be handled the exact same way as other salts, just with a bit more math.
