Ph of weak acids formula
WebbExample. Thus, the pH of an acidic solution of HNO 3 (10 –3 M) = 3, a basic solution of KOH having [OH –] =10 –4 M and [H 3 O +] =10 –10 M will have a pH = 10. pH of acids is … WebbA weak acid is one which doesn't ionise fully when it is dissolved in water. ...

WebbNitric acid, with a pK value of ca. -1.7, behaves as a strong acid in aqueous solutions with a pH greater than 1. At lower pH values it behaves as a weak acid. pK a values for strong acids have been estimated by theoretical means. For example, the pK a value of aqueous HCl has been estimated as −9.3.

It is known to be the active component of vinegar, which is a 4% – 7% solution of acetic acid in water. Acetic acid is a weak acid because it only partially dissociates into its constituent ions when dissolved in water.
WebbAt pH = 7 both amino and carboxylic groups exist in ionised form 4. The reason for lanthanoid contraction is: 1. Negligible screening effect of 'f' orbitals 2. Increasing nuclear charge 3. Decreasing nuclear charge 4. Decreasing screening effect 5. The oxidation states of P in H 4 P 2 O 5, H 4 P 2 O 6, H 4 P 2 O 7, are respectively - 1. +3, +5, +4
