Write a net ionic equation to show that hydroxylamine, NH2OH, behaves as a Bronsted- Lowry base in water. Bases also dissociate in the water like acids, but instead of producing H+ they produce OH- i.e. Chlorine is a electron withdrawing group and its increase the acidity of carboxylic acids by stabilising the conjugate base due to delocalisation of the negative charge by resonance effects.Chloroacetic acid ( Cl-CH2COOH) pKa value is equal to 2.7, while pKa value of acetic acid (CH3COOH) is equal to 4.7. Base liberation and deoxyribonic acid formation, in turn, results in the breakage of the sugar-phosphate backbone, as has been shown by the examination of reaction products obtained from oligodeoxyadenylic acid. The weak base-conjugate acid buffer used in this laboratory consists of a weak base ammonia, NH3, and its conjugate acid ammonium chloride, NH4Cl. … Strong or weak?
