Question

"Adding Acid & Base solutions in a test tube results to....
(i) The temperature of solution increases.
(ii) The temperature of Solution decreases.
(iii) The temperature of the solution remains the same.
(iv) Formation of salt is seen
Alternatives : (A) only (i) correct (B) () & (ii) both correct
(C) (i) & (iii) correct (D) (i) & (iv) correct​

Answer 1

Explanation:

D) (i) & (iv)

acid and base are mixed to give salt and water. This process is exothermic in nature giving out heat called as heat neutrlization which causes an increase in temperature

Answer 2

Answer:

The statements  (i) and (iv) are correct.

Explanation:

• When Acid and Base are added to a test tube, an exothermic reaction is carried out.
• A reaction in which heat is released is called an exothermic reaction. It is characterised by an increase in temperature.
• When acid and base are mixed, a neutralisation reaction occurs. In a neutralisation reaction, water and salt are formed as the end product.

Thus, the statements  (i) and (iv) are correct.
