Water is a polar solvent, but covalent compounds are nonpolar. This implies that covalent compounds don’t dissolve in water and make a separate layer on the surface of the water. Hence we can say that covalent compounds are insoluble in water. Which ionic compounds are not soluble in water? WhichRead More →
Phthalates with a higher molecular weight (HMW) are very slightly soluble in water; phthalates with a lower molecular weight (LMW) are reasonably soluble in water. Most common phthalate added to nail polish. Most widely-added phthalate to polyvinyl chloride (PVC) to make products flexible. Is diethyl phthalate water soluble? Diethyl phthalateRead More →
water and very soluble in boiling water? acetanilide will dissolve into the heated water due to its high solubility in boiling water but will drop out of solution and crystallize in room temperature water due to its low solubility in cold water. Why is acetanilide partially soluble in water? TheRead More →
However, phenol is sufficiently acidic for it to have recognizably acidic properties – even if it is still a very weak acid. A hydrogen ion can break away from the -OH group and transfer to a base. For example, in solution in water: Phenol is a very weak acid andRead More →
MgO is basic and Mg(OH)2 is weakly basic and do not dissolve in NaOH solution. The oxides of calcium, strontium, and barium are basic and the hydroxides are strongly basic. What happens when an amphoteric oxide reacts with sodium hydroxide solution? Yes, amphoteric oxides do react with sodium hydoxide toRead More →
Chloroacetic acid is mainly made by hydrolysing trichloroethylene in the presence of sulfuric acid: CCl2=CHCl + 2 H2O → CH2ClCOOH + 2 HCl. Dichloroacetic acid is manufactured in small quantities by reducing trichloroacetic acid. Is chloroacetic acid optically active? The $2 – $chloroacetic acid has one hydrogen, two chlorine, andRead More →
Carboxylic acids are more soluble in water than alcohols, ethers, aldehydes, and ketones of comparable molecular weight. – They form hydrogen bonds with water molecules through both their C=O. Physical Properties – Water solubility decreases as the relative size of the hydrophobic portion of the molecule increases. Why hexanol isRead More →
A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond. A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. Are ionic bonds polar orRead More →
Lysozyme is an enzyme used to break down bacterial cell walls to improve protein or nucleic acid extraction efficiency. Lysozymes (muramidases) are a family of enzymes with antimicrobial activity characterized by the ability to damage the cell wall of bacteria. How do you prepare 10 mg/ml lysozyme? The base 10Read More →
