IN THE REACTION BETWEEN SODIUM HYDROXIDE AND TETRAOXOSULPHATE (VI) SOLUTIONS, WHAT VOLUME OF 0.5 MOLAR SODIUM HYDROXIDE WOULD EXACTLY NEUTRALIZE 10CM3 OF 1.25 MOLAR TETRAOXOSULPHATE (VI) ACID
The reaction between sodium hydroxide (NaOH) and tetraoxosulphate (VI) solutions can be represented by the following balanced chemical equation: H2SO4 + 2NaOH → Na2SO4 + 2H2O From the balanced equation, it is clear that 1 mole of sulfuric acid (H2SO4)…
