Why does anilin absorb at 230 nm in neutral and 203 nm nm in an acidic medium…

Answer: Aniline in neutral condition has a lone pair which enters into resonance conjugation with benzene ring. This leads to extended delocalization of electrons (beyond what is available in benzene itself). Under acidic conditions, the lone pair is already donated to a

Alkaline Solution - an overview | ScienceDirect Topics

Alkaline solutions erode formation rocks and clays. In some cases, the permeability could be increased owing to the erosion. In most cases, permeability is reduced because eroded rocks and clays migrate and block pore throats. The permeability reduction in low permeability rocks is higher than that in high permeability rocks, as shown in Figure
