<span><span>The column of a fractional distillation apparatus should be
aligned vertical to get better separation because
the column is essentially longer. It will prevent channeling in the
column. </span>Therefore column efficiency will be higher if it is as
vertical as possible instead of tilted.<span> Distillation is a process used to separate a mixture of two (or
more) components. In a typical </span>fractional
distillation, a liquid mixture
is heated in the distilling flask and the
process begins.</span>
Bases
A base is a substance that dissociates into more hydroxide ions (-OH-) when dissolved in water. Bases are also good proton acceptors. Bases, therefore, reduce the number of H+ and increase OH- hence raising the pH of the solution.
B(aq) + H₂O(l) ⇌ BH⁺(aq) + OH⁻(aq)
Explanation:
Other properties of bases is that they are bitter to the taste and they feel slippery when touched. Strong bases are nonthlese very corrosive like acids. Bases turn red litmus paper blue. Most alkali hydroxides such as NaOH are bases.
