Explain the statement "Water has bent geometry"
Water has bent geometry; that is, the H-O-H bond angle is approximately tetrahedral. Repulsion among the lone pairs and the bonds decreases this bond angle somewhat. (The actual bond angle is 104.5°.)
A water solution contains 64% Na 2 S 2 O 2 together with 1.0% soluble impurity. Upon cooling to 5°C, Na 2 S 2 O 2 ·5H 2 O. crystallizes out. The solubility of this hydrate is 1.35

Existence of positively charged nucleus was established by: (1) Positive ray analysis (2) α -ray scattering experiments () X-ray analysis (4) Discharge tube exper
Evaluate the relation between rate constant k 1 and k 2 of a first order reaction when temperature changes from 270 K to 300 K and activation energy is zero?
Q. Determine the Ionization in Solutions? Ans. Ionic compounds dissolve in water because the polar water molecule pulls apart the ions of the ionic compound. This process
