What is the molarity of an H2SO4 solution if 35.00 mL is exactly neutralized by 32.63 mL of 0.164 M NaOH? 2NaOH + H2SO4---> Na2SO4 + 2H20
- 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...
What is molarity of a solution of NaOH prepared by diluting 20.00 mL of 6.0 M NaOH to 500.0 mL? Why can we not calculate the actual molarity of the NaOH solution as indicated in the problems above? Why is an indicator required in the reaction vessel? Which indicator is used?
