PSI Maths & Reasoning Paper Solution Part-1

Assertion (A): Ammonia solution is an alkali. Reason (R ): Ammonia solution turns blue litmus paper red.

Consider the following i. For a solution at atmospheric pressure Psi_(w)=Psi_(s) ii. Psi_(w) (water potential) of a cell is affected by solute potential only iii. Psi_(p) (pressure potential ) is usually positive in xylem during the day which of the statements given above is/are correct?

If Psih_(w)= water potential, Psi_(s)= solute potential, Psi_(p)= pressure potential then select the correct equation showing their inter-relation.

Water potential (Psi) of a solution is always

Compered to 1M sucrose solution, the Psi_(omega) of 1M sodium chlorida solution is
