Question

1. Three beakers labelled as A, B and C each containing 25 mL of water was taken. A small amount
of NaOH, anhydrous CuSO, and NaCl were added to the beakers A, B and C respectively. It was
observed that there was an increase in the temperature of the solutions contained in beakers A and
B, whereas in case of beaker C, the temperature of the solution falls. Which one of the following
statement(s) is (are) correct?
(i) In beakers A and B, exothermic process has occurred.
(ii) In beakers A and B, endothermic process has occurred.
(iii) In beaker C, exothermic process has occurred.
(iv) In beaker C, endothermic process has occurred.
(a) (i) only
(b) (ii) only
(c) (i) and (iv)
fd(ii) and (iii)​
