A 25.0 mL sample of an aqueous solution of calcium hydroxide, Ca(OH)2, is titrated to the equivalence point with 21.2 mL of 0.620 M sulfuric acid, H2SO4, acid solution. What is the molarity of the calcium hydroxide solution?

Sagot :

Let's see

  • C1V1=C2V2
  • 25C1=21.2(0.620)
  • 25C1=13.144
  • C1=0.526M
  • C1/C2=V2/V1
  • C1/21.2=0.62/25
  • C1/21.2=0.0248
  • C1=0.0248(21.2)
  • C1=0.53M
