Sodium sulfate is a strong contributor to the rate of corrosion For example, in water with 400 mg/l of alkalinity (as calcium carbonate) at pH 7, the corrosion rate is zero at 200 mg/l of Na 2 SO 4, but when the concentration of sodium sulfate is 400 mg/l, the corrosion rate is about 100 mg per square cm per dayThe dependence of sodium sulphate solubility on temperature is found to be in accordance with that presented by Shikheeva and Ziranov [6] Fig 4 shows the temperature dependence of the electric conductivity of a given solution This dependence is linear in the temperature range 28815 K for constant concentrationPhysical properties of aqueous solution of sodium sulphate
The concentration of sulfate ion is determined by the titrant volume consumed until it reaches the inflection pointSO₄² ＋ Pb(NO₃)₂ → PbSO₄ ＋ 2NO₃This report introduces an example of the measurement for sulfate ion in bath additive with using lead ionselective electrodeIf we had a saturated solution of sodium chloride at 25 ˚C, we could quote the concentration as 359 grams/L, but because we know the molar mass of sodium chloride (5844 grams/mole), we could also express our concentration as: ⎛⎝(359g) × 1mole 5844g 1L ⎞⎠ = 614moles/L ( ( 359 g) × 1 m o l e 5844 g 1 L) = 614 m o l e s / L74: Concentration and Molarity Chemistry LibreTexts
