Most inorganic acids are also weak but a few are strong. Inorganic acids can also be called mineral acids.
1. Theory. TCA is an analog of acetic acid in which the three hydrogen atoms of the methyl carbon have been replaced with chlorine atoms. TCA is a relatively weak acid so it cannot hydrolyze the peptide bonds of proteins, but it does maintain an acidic pH in water.Addition of TCA to proteins in an aqueous solution disrupts the hydrogen-bonded water molecules (hydration sphere) surrounding a protein.These protein molecules no longer remain soluble and can be recovered by centrifugation..
