Plz tell I will mark as brainliest​

Answer 1

Answer:1 the reaction is neutralization reaction.

Explanation:because HCL is acid and NaOH is a base. when acid and base reacts it forms salt and water i.e. NaCl and H20.

2.i. no change is seen in blue litmus paper because the product is neutral.

ii. no change is seen in red litmus paper because the product is neutral.

3. the solution is basic if it turns pink cuz phenolphthalein doesnt change its colour when it reacts with acid.
