Which of the following is an acid - ammonia - potassium hydroxide - sulfuric acid - lithium hydroxide?
Ammonia (NH3)- when mixed into water - forms a basic solution.potassium hydroxide (KOH)- when mixed into water - forms a basic solution.lithium hydroxide (LiOH) - when mixed into water - forms a basic solution.Sulfuric acid (H2SO4) - when mixed into water - forms an acid solution.
Why ka1of malic acid more than fumaric acid?
Malic acid is more acidic than fumaric acid because malic acid has an additional -OH group compared to fumaric acid, making it more polar and capable of forming stronger hydrogen bonds with water molecules, leading to a higher acidity. Additionally, malic acid can undergo resonance stabilization of the anion formed upon dissociation, further increasing its acidity compared to fumaric acid.
Why is fumaric acid dried in the oven?
Fumaric acid is dried in an oven at a relatively low heat - below 130 degrees centigrade - to evaporate any water that might be left over from formation. If it is heated above 130 degrees, the fumaric acid starts to decompose and form maleic acid, maleic anhydride, carbon monoxide and carbon dioxide. The acid may be dried for a number of reasons. Commercially because water has weight but no value, it is cheaper to transport completely dry fumaric acid. Water may also cause unwanted reactions with other chemicals which the fumaric acid is eventually added to. Removing the water then removes the reactions.
What is formed when ammonia and acetic acid is mixed?
When ammonia and acetic acid are mixed, the result is the formation of the ammonium acetate salt. Ammonium acetate is a white crystalline solid that is often used in organic chemistry reactions and as a buffer solution.
Are nitric acid and ammonia compatible?
Nitric acid and ammonia are not compatible because they can react exothermically to form ammonium nitrate, which is a highly explosive compound. Mixing these two chemicals can be dangerous and should be avoided.
What is an aspartase?
An aspartase is an enzyme which catalyzes the deamination of aspartic acid to fumaric acid and ammonia.
What type of isomers is shown by maleic acid and fumaric acid?
Maleic acid and fumaric acid are cis-trans isomers of each other.
Why is fumaric acid a stable acid?
Fumaric acid being the trans isomer will have the least stearic hindrance as the carboxylic acid groups will be on the different sides of the double bonds-hence causing the least electronic repulsion. Fumaric acid will be more stable as compared to maleic acid.

What has the author John Jacob Kessler written?
John Jacob Kessler has written: 'The nitrile of fumaric acid' -- subject(s): Fumaric acid, Nitriles
Industrial method of preparation of Fumaric Acid?
1. Maleic anhydride is hydrated. This produces maleic acid. 2. Maleic acid is isomerised in the presence of a catalyst. 3. Fumaric acid is produced. Easy as that! (Except the temperature and pressure have to be kept controlled throughout)
Is formation of malic acid from fumaric acid found in the mitochondria?
yes

What is the acid present in carrot?
Malic Acid, Citric acid, Isocitric Acid, Succinic Acid and Fumaric Acid.
What happens if acid is mixed with copper?
it depends what acid it is

Is ammonia plus red cabbage a acid?
Ammonia is a base, not an acid. When mixed with red cabbage indicator, it may turn the solution blue or green, indicating a basic pH.
