Last question answer sodium chloride

[@rajmoi5568]

Q20 it is wrong

[@rajmoi5568]

Is is irreriversable

[@viveksingh3665]

Hydrochloric acid (HCl) + Sodium hydroxide (NaOH) ------> Salt (Nacl) + Water (H20)

[@shivamking4896]

Hi

[@Targetteachership]

20 number question ...it is irreversible in nature As Neutralization reactions are generally not reversible under standard conditions. In a neutralization reaction, an acid reacts with a base to form water and a salt. For example: \[ \text{HCl} + \text{NaOH} ightarrow \text{NaCl} + \text{H}_2\text{O} \] In this case, hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) to produce sodium chloride (NaCl) and water (H₂O). Once the products are formed, they do not typically revert back to the original acid and base under normal conditions. However, in certain special cases and under specific conditions, it is possible to reverse the reaction. For example, in the case of weak acids and bases in aqueous solutions, the reaction can be somewhat reversible, and an equilibrium can be established. But in practice, for strong acids and bases, the neutralization reaction is effectively considered irreversible.

[@saraswatiojha5561]

Thank you so much sir for this message ❤🎉

[@otitumhih]

Neutralization reaction is a chemical change and cannot be reversed please check question no 20

[@piyukumar6576]

Hcl +Naoh -->NaCl +H2o neutrilaization

[@gitanjalikumari7617]

Hello sir I have doubt I learn nuetralisation reaction is always chemical change and not reversible change so according to me answer of question 20 is (D)

[@Nileshgreninja-]

Now you are wrong beta

[@naikdurjadhan8816]

[@Anmol__Singh]

Neutralistion

[@kuberffyt804]

Sodium chloride + water

[@raosahab111]

When a salt such as sodium chloride dissolves in water it breaks up into positively- and negatively-charged ions. Sodium chloride breaks up into sodium and chloride ions in water. Every water supply contains some sodium and chloride.

[@raosahab111]
