51. Solving a chemistry problem

69. Before using river water in production, it is clarified, for which it is possible to use various electrolytes that cause coagulation of silt particles. Calculate the consumption of electrolyte - coagulator (kg / day), if the water consumption at the enterprise is 100,000 m3 / day, and the sign of the charge of suspended particles of sludge is positive:
69. The coagulation threshold for NaOH is 45 mol/m3. What will be the electrolyte consumption when replacing NaOH with Na3PO4?
