Equations are developed that permit the calculation of the mean ionic activity coefficients of H +, H +, SO 4 2− (γ 1′ and of H +, HSO 4 −(γ 2′) from the measured practical activity coefficient of sulphuric acid, if α (the fraction of total sulphate as SO 4 2−) ...
One-third of the world’s sodium sulphate is produced as a by-product of other processes in the chemical industry. It is produced by the reaction of sodium chloride and sulphuric acid. 2 NaCl + H2SO4→ 2 HCl + Na2SO4 The crystals were used as a general-purpose laxative, until the ...

To solve the question regarding the indicator used in the titration of sodium carbonate with sulfuric acid, we can follow these steps:1. Identify the Reactants: - The reactants in this titration are sodium carbonate (Na2CO3
Phase relationships in the sodium sulphate – sulphuric acid and sodium pyrosulphate – water systemsPhase diagrams for the Na2SO4-H2SO4 and Na2S2O7-H2O systems were determined from the melting points of samples of various compositions. High-purity materials were used and the melting points were ...
