It is more likely to be called a precipitate.
The chemical structure of phenobarbital is:The aromatic ring and methyl group will be more favorable for organic solvent, while the NH in the ring and O attachments favor aqueous solvents.One gram is soluble in approximately 1000 ml of water, and 10 ml of alcohol. Compared to other barbiturates it has a lowlipid solubility. It is very soluble in water, soluble in alcohol, and freely solu­ble in propylene glycol. In other words, the question makes an incorrect assumption - phenobarbital is MORE soluble in aqueous solvents than in organic solvents.
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
The advantage of non-aqueous media titrations is that often the end point is much more satisfactory to the person doing the experiment. Another advantage is that mediums that are not soluble in water can be used.
Adding more solute to a saturated solution causes the solution to become supersaturated. In other words, the solvent does not completely mix with the solute.
Phenol is acidic in nature. The phenolate anion is stable through resonance. Hence, an acid base reaction ensues between phenol and NaOH in water resulting in the formation of sodium phenolate, which is highly soluble in water compared to phenol.
There are many chemicals aqueous with water, for example: Sodium Chloride (basic table salt) is. To find more check with solubility rules, if it says the the substance is soluble, then it is aqueous with water.
yes
Benzene, being a covalent compound is not soluble in water. So a solution of benzene in water is absurd. However in answering your question I would say that, as benzene is not soluble in water it does not function as an electrolyte. Some more improvement would be that benzene itself is not an electrolyte.
Magnesium hydroxide is more soluble in an acidic solution.
Yes. You can add more solute to make it more concentrated, or if some of the solvent (water) evaporates it can become more concentrated. If you add additional water, it will become less concentrated.
Benzoic acid is only slightly soluble in water. When warmed up it will dissolve. It can then be filtered and cooled down and the benzoic acid will crystallize out. This is a method use to purify the substance.
Most probably Caesium hydroxide is about 3 times more soluble than NaOH Solubility (in water) CsOH: 300 g/100 mL at 30 °C) Solubility (in water) NaOH: 111 g/100 mL at 20 °C
No, it is not correct.
BaCO3 would be more soluble in an acidic solution than in the water
It is more likely to be called a precipitate.
Any type of base that has one or more OH- ions in it and is soluble in water will release hydroxide ions in aqueous solution. Example:NaOH + H20 --> Na+ + OH-
