Question

K. Select the incorect statement 1 ( Reaction of sodium hydronide with dillut hydrochloric acid isa displacement reaction Reaction with copper cide with dilute hydrochloric acid is a double displacement reaction Reacioni sodium hydroxide with dilute hydrochloric acid isaneutralization reaction () Reaction of copper aide with dilute hydrochloric acid isa neutralization reaction O a) Only 0 O (6) Only) O (c) Both ) and (iv) O (d) Both (m) and (m)​

Answer 1

Answer:

in answer u will find (d) Both (ii) and (iv)

but actually its (i)

Acid + Base is a double displacement as well as neutralisation reaction...

please mark it as brainlist

Answer 2

Answer:

The incorrect statement is (1) reaction of sodium hydroxide with dilute hydrochloric acid.

Explanation:

• An acid-base reaction is always neutralization reaction which is a specific kind of double displacement reaction.
• In a double displacement reaction, two compounds react by exchanging ions to produce two new compounds. Like

$AB+CD$→$AC+BD$

• In a displacement reaction, a more reactive element removes a less reactive metal from its compound.

$A+BC$→$AC+B$

• Here, sodium hydroxide is a strong base and hydrochloric acid is a strong acid, be it diluted, react to give sodium chloride (salt) and water. This is a case of double displacement or neutralization.

$NaOH+HCl$→$NaCl+H_{2}O$

$Na^{+}OH^{-}+H^{+}Cl^{-}$→$Na^{+}Cl^{-}$

• You can see that there is exchange of ions. Hence, it is a double displacement reaction.

Conclusion:

The statement (1) reaction of sodium hydroxide with dilute hydrochloric acid is incorrect.
