Since phosphoric acid, represented by the molecular formula H3PO4, has three hydrogen atoms, it dissociates three times, into H 2 PO 4-, HPO 4 2-and PO 4 3-. The pKa value is based on the Ka value, which is called the acid dissociation constant.

I need to determine the Ka values of H3PO4 having titrated a solution of H3PO4 and HCl with 0.1142 M NaOH. The concentrations of H3PO4 and HCl were found to be 0.106 M and 0.003 M respectively. The first EP was reached at 4.76 mL with a pH of 4.65 and the second EP was reached at 9.41 mL and a pH of ...

The Ka values of H3PO4 are shown below. Ka1 7.5 X 10^-3 Ka2 6.2 X 10^-8 Ka3 4.8 X 10^-13 Thank you in advance!

Ka of H3PO4= 7.5 X 10^-3 Ka of H2PO4= 6.2 X 10^-8 Ka of HPO4= 4.8 X 10^-13 Both of these solutions are basic since potassium comes from KOH, which is a strong base and the anions are weak acids.

1. Strong acids are listed at the top left hand corner of the table and have Ka values >1 2. Acid with values less than one are considered weak. 3. The strong bases are listed at the bottom right of the table and get weaker as we move to the top of the table.

Phosphoric acid is a sequestering agent which binds many divalent cations, including Fe++, Cu++, Ca++, and Mg++. Phosphoric acid is used in dentistry and orthodontics as an etching solution, to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed.

What Is the Ka Value of HNO3? The Ka value of HNO3 is about 24. HNO3 is the chemical formula for strong nitric acid. The Ka value, also known as the acid dissociation equilibrium constant, is a measure of the acidity of a solution. Strong acids, such as HNO3, have a Ka value that is greater than one. Acids with a Ka below one are known as weak ...
