An acid–base titration is a method of quantitative analysis for determining the concentration of Brønsted-Lowry acid or base (titrate) by neutralizing it using a solution of known concentration (titrant). [1] A pH indicator is used to monitor the progress of the acid–base reaction and a titration curve can be constructed. [1]
The Sørensen formol titration(SFT) invented by S. P. L. Sørensen in 1907 [1] is a titration of an amino acid with potassium hydroxide in the presence of formaldehyde. [2] It is used in the determination of protein content in samples. [3] Formol titration equation for amino acids in general
The buffering region is dependent upon the pKa, and is typically +/- 1.0 pH units of the pKa. The pKa of KHP is 5.4, so its pH buffering range would be 4.4 to 6.4; however, due to the presence of the second acidic group that bears the potassium ion, the first pKa also contributes to the buffering range well below pH 4.0, which is why KHP is a ...
4 (aq) → Ag 2 CrO 4 (s) (K sp = 1.1 × 10 −12) The solution needs to be near neutral, because silver hydroxide forms at high pH, while the chromate forms Ag 2 Cr 2 O 7 or AgHCrO4 at low pH, reducing the concentration of chromate ions, and delaying the formation of the precipitate. Carbonates and phosphates precipitate with silver, and need ...
[1] Later in his career, Brønsted kept studying reaction kinetics, with a special focus on reactions taking place in non-aqueous solutions . He also developed some work about the effect of molecular size on the thermodynamical properties of hydrocarbons, polymers and colloids. [ 7 ]
