Is acetone and acid or base?
Acetone is categorized as a very weak acid; its pKa value is equal to 19.3 (the higher the pKa value, the weaker the acid. For comparison, HCl’s pKa value is -7). The pKa value of water, which is a neutral compound, is around 15.74. The acidity of acetone is much smaller than that of water.
Is acetone an acidic acid?
Acetone is a weak Lewis base that forms adducts with soft acids like I2 and hard acids like phenol.
Does acetone react with bases?
All Answers (4) Acetone, when in basic medium, undergoes condensation reaction to form yellow cyclic unsaturated keto-compound, commonly called isophorone.
Is acetone a Bronsted Lowry acid or base?
Acetone is a Lewis base and a Brønsted base.
Why is acetone a strong base?
Why doesn’t acetone have high basicity? The C−O bond is polar, O becomes partially negatively charged and it should attract protons, becoming a strong base.

What is the pH level of acetone?
80% water/acetone ratio was chosen from Figure 3 for the following characterization since the absorbance is relatively large and solubility is not an issue. The pH of HNQ solution is slightly acidic, 4.7.

What happens when acetone is mixed with water?
When acetone is mixed with water it completely dissolves in it. In this type of reaction acetone is usually the solute and water is the solvent. When these two compounds are mixed there is a formation of hydrogen bonds resulting in a homogeneous solution. Was this answer helpful?
Does acetone react with acids?
Acetone + Acid will yield in first a yellow-brown solution which will precipitate some black stuff and eventually if you wait long enough for the Acetone to evaporate you will get a red-black oil.
What happens when acetone reacts with NaOH?
Acetone contains alpha hydrogen atom. hence, when it is heated with dil NaOH solution, it undergoes aldol condensation reaction to form 4-methyl pent -3-en-2-one .
Why acetone is Lewis base?
Acetone is a Lewis acid because the double bond attached to the oxygen attracts unpaired electrons from other molecules. A Lewis acid is very similar to an oxidizer. If the double bond contributed an unpaired electron to another molecule, then the molecule would be a Lewis base.
Is acetone a stronger acid than water?
For acetone, pKa 19.2, the equilibrium lies further on the non-dissociated side than for water. We take this to mean that acetone is a weaker acid that water.
Why acetone is a good solvent?
Acetone is a good solvent due to its ability to dissolve both polar and nonpolar substances, while other solvents can only dissolve one or the other. Acetone’s chemical makeup includes elements that are both polar and nonpolar which means acetone can be used with both organic and inorganic substances.
Is acetone chemically stable?
Chemical Stability: Normally stable. Conditions to Avoid: Open flames, sparks, static discharge, heat and other ignition sources.
Is acetone an organic acid?
Acetone, propanone or dimethyl ketone, is an organic compound with the formula (CH3)2CO. It is the simplest and smallest ketone. It is a colourless, highly volatile and flammable liquid with a characteristic pungent odour.
What does acetone not mix with?
Acetone may form explosive mixtures with chromic anhydride, chromyl chloride, hexachloromelamine, hydrogen peroxide, nitric acid and acetic acid, nitric acid and sulfuric acid, nitrosyl chloride, nitrosyl perchlorate, nitryl perchlorate, permonosulfuric acid, potassium tert-butoxide, thiodiglycol and hydrogen peroxide.
What happen when acetone reacts with iodine and base?
Acetone has a chemical formula (CH3)2CO . It is also known as propanone or dimethyl ketone and it is the smallest and the simplest ketone. When it reacts with iodine in presence of NaOH, it forms iodoform. So, we can see that iodoform is formed in the presence of NaOH.
How does acetone react with HCl?
In presence of dry HCl, two molecules of acetone undergo aldol condensation reaction to form mesityl oxide.
