Supercooling<span>, a state where liquids do not solidify even below their normal freezing point. Means sometimes we have liquid water below 0 degree C.</span>
Answer:
Explanation:
KHT is a salt which ionises in water as follows
KHT ⇄ K⁺ + HT⁻
Solubility product Kw= [ K⁺ ] [ HT⁻ ]
product of concentration of K⁺ and HT⁻ in water
In KCl solution , the solubility product of KHT will be decreased .
In KCl solution , there is already presence of K⁺ ion in the solution . So
in the equation
[ K⁺ ] [ HT⁻ ] = constant
when K⁺ increases [ HT⁻ ] decreases . Hence less of KHT dissociates due to which its solubility decreases . It is called common ion effect . It is so because here the presence of common ion that is K⁺ in both salt to be dissolved and in solvent , results in decrease of solubility of the salt .
Answer:
lower energy that helps the balance
Answer:
trans-4-tert-butyl-1-phenylcyclohexanol
Explanation:
The bulky tert-butyl group will occupy the equatorial position in the cyclohexanone ring.
It will hinder approach of the Grignard reagent from the bottom side of the molecule.
The reagent will attack from the top, so the product alcohol will be
<em>trans</em>-4-<em>tert</em>-butyl-1-phenylcyclohexanol.
