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 as well as its purity is 96%. The base added is 100% pure. Approximate the final pH and the final TDS in mg/L of the mixture of the two baths
