3.1. How would you determine the standard electrode potential of the system Mg2+1 Mg?Ans: A cell will be set up consisting of Mg/MgSO4 (1 M) as one electrode and standard hydrogen electrode Pt, H, (1 atm)H+/(l M) as second electrode,…
2.1. Calculate the mass percentage of benzene (C6H6) and carbon tetrachloride (CCl4) if 22 g of benzene is dissolved in 122 g of carbon tetrachloride.Ans: Mass of solution = Mass of C6H6 + Mass of CCl4= 22 g+122 g=…
1.1. Why are solids rigid?Ans: The constituent particles in solids have fixed positions and can oscillate about their mean positions. Hence, they are rigid. 1.2. Why do solids have definite volume?Ans: Solids keep their volume because of rigidity in…
