Malonic acid has pKa values of 2.83 (pK1) and 5.69 (pK2). If malonic esters are used then on treatment with a strong base like sodium ethoxide, the methylene (-CH2-) hydrogen can be deprotonated, but I am not sure if that is possible for malonic acid as that will lead to a tri-anion.
What else can I help you with?
How many protons can be lost by citric acid H3C6H5O6?
Three. Sometimes the formula is written H3C6H5O7 to indicate that.
How many protons does Zn positive 2 charge have?
Zinc (Zn) typically has 30 protons in its nucleus. However, with a positive 2 charge, it has lost two electrons, leaving it with a net charge of +2. This does not change the number of protons, which remains at 30.
Is it true or false in the formation covalent or ionic bonds is it the protons that are shared gained or lost?
In covalent bonds, electrons are shared between atoms, not protons. In ionic bonds, one atom loses electrons (becomes positively charged) and another atom gains those electrons (becomes negatively charged), but protons remain inside the nucleus and are not shared, gained, or lost in the bond formation process.
Can you form ions of the same element by changing the number of protons?
No. As the number of protons changes, the identity of the element changes and new elements are formed.Ions are formed only when electrons (and not protons) are gained or lost.
What happens to each of the functional groups on an amino acid when the amino acid becomes an ion?
When an amino acid becomes an ion (by gaining or losing a proton), the amino group (NH2) becomes NH3+, the carboxyl group (COOH) becomes COO-, and any side chain functional groups may be affected depending on their specific properties. The net charge of the amino acid will depend on the balance of protons gained or lost.
Why there is loss in mass reaction of baking soda and acetic acid?
Mass isn't lost, it just escapes as a gas
How many protons can be lost by citric acid H3C6H5O6?
Three. Sometimes the formula is written H3C6H5O7 to indicate that.
How ch3 group replace h proton in acetic acid?
I think its through esterification, so react with methanol, CH3OH. The H from your acid should be lost along with the OH in the alcohol as H2O
What is the species that remains when an acid has lost a proton in a conjugate?
Conjugate acid
Why can't oxygen be changed into helium?
Oxygen has 8 protons, helium has 2 protons. To convert oxygen to helium, 6 protons has to be lost by nuclear disintegration which is not possible.
If an atom has lost more protons than electrons it is called a ion?
If an atom has lost more protons than electrons, it becomes a positively charged ion. This is because it now has more positive charge (from the protons) than negative charge (from the electrons), leading to an overall positive charge.
How many electrons are lost or gained if there are 4 electrons 4 protons?
If there are 4 electrons and 4 protons, the atom is electrically neutral since the positive charges from the protons balance out the negative charges from the electrons. No electrons are lost or gained in this scenario.
Which of these particles are lost in the oxidation process protons neutrons electrons atoms?
Electrons are these particles.
What is the species that remains when an acid has lost a proton?
The species that remains when an acid has lost a proton is called the conjugate base of the acid. It is formed by the acid donating a proton (H+) and becoming negatively charged. The conjugate base has one less proton compared to the original acid.
What happens if the elements have different protons and electrons?
A neutral atom of a chemical element has a constant number of protons and electrons; loss or gain of electrons transform this atom in an ion.After the change of the number of protons the identity of the atom is lost.
How many protons does Zn positive 2 charge have?
Zinc (Zn) typically has 30 protons in its nucleus. However, with a positive 2 charge, it has lost two electrons, leaving it with a net charge of +2. This does not change the number of protons, which remains at 30.
