exists and is an alternate of .

There are two answers: bicarbonate has two pKa's - because bicarbonate can gain a proton to become carbonic acid or lose a proton to become carbonate. Two reactions; two pKa's. The pKa for bicarbonate <-> carbonic acid reaction is 6.4 The pKa for bicarbonate <-> carbonate reaction is 10.3 Both pKa's are temperature sensitive.

Who sells sodium bicarbonate powder?

Answer . Sodium bicarbonate is commonly known as baking soda , and can be bought in most grocery stores or drug stores.

How do you determine the pKa value of a compound?

Use a method called titration , where a known concentration of either a strong acid (to measure a weak base) or a strong base (to measure a weak acid) is slowly added to a solution of the unknown compound. By measuring the pH of the solution as you do the titration, and by measuring the volume of t ( Full Answer )

What is the chemical formula for sodium bicarbonate?

Sodium bicarbonate, also called sodium hydrogen carbonate andcommonly known as baking soda, has NaHCO 3 for a chemicalformula. Use the link below to check facts and learn more.

What is the pH of sodium bicarbonate?

Sodium bicarbonate at room temperature is very hard to calculate but a good approximation will be a pH value of around 8. http://www.pburch.net/dyeing/FAQ/sodaash.shtml http://www.hometrainingtools.com/articles/acid-base-reactions-ph-experiments.html

What is the balanced equation for sodium bicarbonate?

I assume you mean you want the molecular formula for sodium bicarbonate - if you wanted a balanced equation, you would need another substance to react with But sodium bicarbonate = NaHCO 3 While the above answer is help full I am going to assume that the question was what is the balanced equation ( Full Answer )

Pka value of phosphoric acid?

2.14, 6.86 and 12.4 - phosphoric acid is a polyprotic acid, meaning that it can dissociate more than one hydrogen ion.

What is the pH level of sodium bicarbonate?

Sodium bicarbonate (baking soda) - according to the websites listed below, the pH level is at 8.3.. http://wow.osu.edu/experiments/chemistry/pH.html http://chemistry.about.com/od/acidsbases/a/phtable.htm

What is pH value for sodium bicarbonate?

There is no way to know the pH of sodium bicarbonate unless the concentration of [H+] or [OH-] is known. If the concentration is known, pH can be calculated as the -log[H+], or 14-(-log[OH-]).

What is the pka of sodium chloride?

Pka, (acid-ionization constant) is a measure of strength of an acid in a solution and is the equilibrium constant chemical reaction dissociation in acid based reactions. Sodium chloride or "table salt" has strong bases and acids and would not need Pka.

Is sodium bicarbonate a element or compound?

Elements are the substances you see in the Periodic Table. Compounds are the result of different elements coming together. In the case of sodium bicarbonate, the formula is NaHCO 3 . This substance has 4 different types of elements. Thus, it is a compound.

What is a molecular structure for sodium bicarbonate?

There is no molecular structure for sodium bicabonate because sodium bicarbonate is not a molecule, it is an ionic compound made up of sodium cations (Na+) and bicarbonate anions (HCO3-). However, since bicarbonate is a polyatomic anion that is held together by covalent bonds, it is possible to draw ( Full Answer )

PKa value of KH2PO4?

6.7 although it still most likely has another one that I am not quite sure of maybe around 1-2

Does sodium bicarbonate have salt in it?

It actually is a type of salt and contains Sodium expressed (NaHCO3). Common table salt is different, Sodium Chloride expressed (NaCl) . Sodium is Na+ . Sodium Bicarbonate is Na HCO 3 - . Raw table salt is NaCl -

Is sodium bicarbonate harmful?

Ingestion of excessive sodium bicarbonate (more than 2 teaspoons a day) can lead to a metabolic alkalosis. This is a serious condition that can require hospital admission for breathing support. People with poor kidney function may become alkalotic with less than this amount as their bodies are less ( Full Answer )

What pka value for sodium chloride?

Sodium chloride, NaCl, is not an acid so it does not have a Ka orpKa value. Sodium chloride is a neutral salt.

What does the pKa value stand for?

It refers to the acidity of the fatty acid (which make up the oils). Every fatty acid is composed of a non-polar long chain of hydrocarbons (carbon and hydrogen) and a polar head made up of Carboxylic ACID. Every acid has something called pKa which determines the acidity of that acid. The bigger th ( Full Answer )

Are sodium carbonate and sodium bicarbonate the same?

No. Sodium carbonate is Na 2 CO 3 (also called washing soda) while sodium bicarbonate (also called sodium hydrogen carbonate or baking soda) is NaHCO 3 . Sodium carbonate is a stronger base than sodium bicarbonate.

Can you swim after adding sodium bicarbonate?

It is used in medicine for treating kidney problems, but for swimming in it... not quite sure. If too much dosage for medical means causes headaches, nausea, and irritability. Swimming in it shouldn't cause much problems, just do it at your own risk.

What is pKa value of aminoacids?

The pKa values of Amino acids depends on its side chain. However, the protonated amine group (NH 3 + ) tends to have a pKa greater than 8.8, whereas the carboxylic acid (COOH) tends to have a pKa of 1.8 - 2.8. If you keep your amino acid at a pH between this value, you will likely have a Zwitter io ( Full Answer )

What is definition of pka value and difference between pH and pKa?

A pKa value is a measurement used for bases and acids. Themeasurement pH applies to hydronium ion concentrations that are ina solution, whereas pKa only applies to determining the amount ofdissociation an acid wants to do in a solution.

What is the action of sodium bicarbonate in mouthwash?

In mouthwash, Sodium bicarbonate is used as an ingredient. It works as a mechanical cleanser on the teeth and gums, neutralizes the production of acid in the mouth and also as an antiseptic to help prevent infections occurring.

What is the pka of sodium benzoate?

From this salt the benzoate ion C6H5-COO - is a base ( the other part Na + is neutral). This base has a pK B value of 9.80 ( benzoate ) The pK a cid value of its conjugated benzoic acid ( C6H5-COOH) however is pK benzoic -acid = 4.20 = pK a (which is (not surprisingly) equal to ( Full Answer )
