Conc. $HN{O_3}$
Given below are two statements :
Statement $I$ : Gallium is used in the manufacturing of thermometers.
Statement $II$ : A thermometer containing gallium is useful for measuring the freezing point ( $256 \mathrm{~K}$ ) of brine solution.
In the light of the above statement, choose the correct answer from the options given below :
Correct Lewis acidity order of $BX_3$ is
When $BCl_3$, is treated with water, it hydrolyses and forms $[B(OH)_4]^-$ only whereas $AlCl_3$ in acidified aqueous solution forms $[Al(H_2O)_6]^{3+}$ ion. Explain what is the hybridizations of boron and aluminum in these species?
Aluminium trifluoride is insoluble in anhydrous $HF$ but dissolves on addition of $NaF$. Aluminium trifluoride precipitates out of the resulting solution when gaseous $BF $$_{3}$ is bubbled through. Give reasons.
