How to Make a Citric Acid Buffer Solution

A citric acid buffer works in the same way as a sodium citrate buffer To make this you need both citric acid and the conjugate base sodium citrate Citric acid is a weak organic acid that occurs naturally in citrus fruits and can efficiently maintain a pH from 3 to 6 2 Sodium citrate is the sodium salt of citric acid with alkanizing activity

Acidity of Solutions of Amphiprotic Substances

The term amphiprotic in modern acid-base chemistry is the replacement for the older term amphoteric An amphiprotic substance is a substance which can act both as an acid and as a base participating in two acid-base equilibria because it contains at least one proton which can be given up and at least one site at which a proton can be acquired

Acidity or Basicity of Salt Solutions?

3/5/2010Since Ka = Kb the salt solution is essentially neutral NH4CHO2 comes from NH3 and HCHO2 Kb NH3 = 1 8 x 10^-5 Ka HCHO2 = 1 8 x 10^-4 Since KaKb the salt solution is acidic Na2HPO4 comes from NaOH and H2PO4- Since NaOH is a strong base and H2PO4- is a weak acid the salt solution is basic Na2C2O4 comes from NaOH and H2C2O4
