Answer #1

1 d

Water molecules have cohesive forces within themselves which helps them to make a continuous column during water transport.

5 c

When sodium chloride dissolves in water, it breaks into sodium ion and chloride ion respectively.

6. C

The Hydrogen ion concentrations for the given solution is 0.001 M. The pH of this solution will be 3 which is acidic. The acidic solution acts as Hydrogen ion donar.
