- What is the molarity of a solution in which 0.051 grams of sodium thiosulfate is prepared in a solution having a total volume of 200.00 mL Neutralization is the reaction between an acid and a base, producing a salt and neutralized base. For example, hydrochloric acid and sodium hydroxide form sodium chloride and water: HCl(aq)+ NaOH(aq) H2O0+NaCl(aq) a. Using the previous reaction, if 35 ml of 0.1 M NaOH will neutralize 10 mL of HCl, what is the concentration...
