2NE1 Gets Sentimental, CL Gets Naked in 'Missing You': Watch
Dressed in fashionable, at times witch-like, winter gear, the girls spend most of the video on the verge of tears singing the heartbreakingly bitter lyrics. I love that song. But "Missing You" is just a striking, perhaps more so, even without a simple hook. They enhance the likeliness of formation of phenoxide ion. Water is a polar solvent. However the polarity of this part too increases in phenoxide ion. Hence is more soluble in water.

Solubility of phenols in alkalies Why phenols are soluble in alkalies? The acidic nature is due to formation of resonance stabilized phenoxide ion formed by losing a proton from -OH group. Thus more and more phenol is converted to phenoxide ion that is soluble in water. Water is a polar solvent. Hence polar substances like salts are more soluble in it.
Phenoxide ion is more polar than phenol itself. Hence is more soluble in water. Where from this water has come? We are adding alkalies and not water? In general, when we are adding alkalies means we are adding their aqueous solutions and not the pure compounds.
What about the solubility of phenol in water? Is it soluble in it? Phenol is also soluble in water to some extent. It is due to its ability to form hydrogen bonding with water molecules. However the large part of phenol molecule is phenyl group that is non polar and hence its solubility if limited in water. However the polarity of this part too increases in phenoxide ion.
But phenol is not soluble in aqueous solution of NaHCO3. NaHCO3 is not strong alkali and hence it cannot provide as much OH- ions that are required to shift the above mentioned equilibrium.
The two stood embraced, in a pool of warm fresh blood. The CDC knows the truth. Jeff moved the knife vertically, straight up, slicing though her stomach. She was an intravenous drug user. She lifted my balls in her hand, and placed her wet, warm mouth over the bulb of my dick, rhythmically sucking it.
If Kahn's model is correct, redirecting the 540 million now wasted on spreading the myth of heterosexual AIDS to high-risk groups - mostly gays and inner-city drug users - could wipe out new infections entirely.
It was a mess with boxes everywhere, obviously they hadn't finished moving in yet. Yet this year, its education program, "Respect Yourself, Protect Yourself" is once again aimed at the general population.
