Who prepared the H.D. report in India ? What are its units of analysis ?
K_(a) values for HA,HB and HD are 10^(-5), 10^(-7) and 10^(-9) respectively. Which of the following will be correct for decimolar aqueous solutions of NaA, NaB , and NaD at 25^(@)C ?
Four acids HA,HB,HC and HD form salts with NaOH of Ph 7,8,9 and 10 respectively when each solution was 0.1M , the strongest acid is :
In,the given figure,if BD=DC,BE=ED,AH= HD and DF Il CG.Find the value of ( areaof /_FEG)/(areaof/_ABC)
In the diagram AD = DB and AH = HD Find the ratio of the area of the shaded portion to that of the triangle DEF, if DE || BC and HG || AE
