After dilution, a concentrated solution of sodium hydroxide or sodium carbonate can be slowly added a few milliliters at a time while vigorously stirring until the pH reaches between 4 and 10. If using carbonates as a neutralizing agent, be aware that bubbling and foaming may occur, leading to additional splash and spill hazards. Once the solution has been neutralized to within a pH of 4-10, the solution can be disposed of via a drain that leads to the sanitary sewer system with copious amounts of water. s8fp4s5?#KHR+yqH1r%Dn$21{m#PetMr7FwfKJ7A9h" 5{kglY Ur>R>!SSgGraap;g{MzH_IJ;$9)TKmVA_ aS5nrut71|dfO*$zCd^8RV,X{5Y=I:sECD;-uK k(~%D!{lC?
