It has been proposed to mix a 1500 L bath containing 5% by volume of H2SO4 with a 1500 L bath containing 5% by weight of NaOH. The Specific gravity of the acid added is 1.841 and its purity is 96%. The base added is 100% pure. Estimate the final pH and the final TDS (in mg/L) of the mixture of the two baths
