So, to convert normality to molarity or vice-versa in the case of CaCl2, you know that a 1 M solution will generate a 2 M solution of chloride ions and a 1 M solution of Ca2+ions, which because of their charge also have a value of 2 for n. So in this case, N = (1 M)(2)...
Lignin isolation process is done by usingan alkaline hydrogen peroxide solution. A total of 20 grams of rice husk is inserted in the neck of the 500 ml flask, then add 120 mL demineralized water containing 1% H2O2 (volume/weight ratio of 1: 6). Add 2N NaOH until pH of 9. How do yo...
