Question

Observe the following diagram and answer the following questions:

1. Write the names of the reactants taking part in the chemical reaction, with formula.

2. List the observation which justify that a chemical reaction has taken place.

3. Write a word equation and a balanced chemical equation for the complete chemical reaction that has taken place .


4. Write a generalised equation for a neutralisation reaction . 5. Does pH of a solution change with dilution .​

Answer 1

Answer:

1) HYDROCHLORIC ACID (HCl) and SODIUM HYDROXIDE (NaOH)

2) AFTER REACTION WE CAN SEE FORMATION OF WATER AND SALT (NaCl) IN THE CONICAL FLASK AND TEMPERATURE OF THE FLASK ALSO RISED BECAUSE NEUTRALISATION IS AN EXOTHERMIC PROCESS.

3) SODIUM HYDROXIDE + HYDROCHLORIC ACID GIVES SODIUM CHLORIDE (SALT) + WATER

NaOH + HCl gives NaCl + H20.

4) NaOH + HCl gives NaCl + H20.

OR

SODIUM HYDROXIDE + HYDROCHLORIC ACID GIVES SODIUM CHLORIDE (SALT) + WATER

5) Ph of the solution changed from basic to neutal because of formation of NaCl
