Tert-butyl alcohol's 13C-NMR spectrum will only display two signals.
(I) Signal at about 31 ppm: This signal is for the more shielded and electron-rich carbon atoms and is upfield. The height of the peak on the y-axis indicates the relative quantity of carbon atoms to other peaks. Since it is three times as tall as the second signal in this instance, it is clear that this peak represents three carbon atoms.
(ii) Signal at about 70 ppm: This signal is directed downfield and pertains to the carbon atom, which is more exposed and has an environment poor in electrons. The height of these peaks is only one carbon higher than the second signal. Furthermore, the exposed environment demonstrates this carbon.
If pH is increased then concentration of increases in solution resulting removal of by forming . Hence, according to Le-chatelier principle, equilibrium will shift towards right. So more will dissolve
If is added then concentration of increases in solution resulting shifting of equilibrium towards left in accordance with Le-chatelier principle. So less will dissolve
Insoluble precipitate of AgOH is formed by adding NaOH in solution resulting removal of . So, more will dissolve
