The correct Answer is:
To solve the question regarding the assertion and reason, we will analyze both statements step by step. ### Step 1: Analyze the Assertion **Assertion:** HCl, HNO3, and H2SO4 are equally strong acids in water. - **Explanation:** - HCl (hydrochloric acid), HNO3 (nitric acid), and H2SO4 (sulfuric acid) are all classified as strong acids. - Strong acids are defined as those that completely dissociate in water to produce H+ ions. - When these acids are mixed with water, they dissociate completely, meaning that all of the acid molecules break apart into their constituent ions (H+ and their respective anions). - Therefore, in an aqueous solution, HCl, HNO3, and H2SO4 behave similarly in terms of their ability to donate protons (H+), making them equally strong acids in water. **Conclusion:** The assertion is correct. ### Step 2: Analyze the Reason **Reason:** Water is a stronger acid than alcohols. - **Explanation:** - Water (H2O) can dissociate into H+ and OH- ions. - Alcohols, which have the general formula R-OH (where R is an alkyl group), have an -OH group that is less likely to release H+ due to the electron-donating effect of the alkyl group (R). - This electron-donating effect stabilizes the -OH group in alcohols, making it more difficult for the hydrogen ion (H+) to dissociate. - Therefore, water is indeed a stronger acid than alcohols because it can more readily donate H+ ions compared to alcohols. **Conclusion:** The reason is also correct. ### Step 3: Determine the Relationship between Assertion and Reason - While both the assertion and reason are correct, the reason does not explain the assertion. The assertion discusses the strength of certain strong acids in water, while the reason compares the acidity of water to alcohols, which is a separate topic. ### Final Conclusion - Since both the assertion and reason are true, but the reason does not explain the assertion, the correct option is: **Option 2:** Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

Alcohols are weaker acids than water. Why ?

Assertion: Heat of neutralization of HF acid is more than that of HCl acid by a strong base. Reason : HCl is stronger acid than HF

(A): HBr is stronger acid than HI. (R) : Bromine is more electronegative than iodine.

Alcohol are stronger acids than alkanes. This is clear from the reaction

A : pH of 10^(-8) M HCI solution is approx 6.9 R : HCI is a strong acid.

Assertion (A): BaCO_(3) is more soluble in HNO_(3) than in water. Reason (R ): Carbonate is a weak base and reacts with H^(o+) ions to form strong acid causing barium salt to dissociate.

Statement-1: It is difficult to distinquish the strengths of the strong acids such as HCl, H_2SO_4,HNO_3, HBr, HI or HCIO_4 in dilute aqueous solutions. Statement-2 : In dilute aqueous solution all strong acids donate a proton to water and are essentially 100% ionised to produce a solution containing H_3O^(+) ions plus the anions of strong acid.

A : CO_2 is a Lewis acid. R : H_2SO_4 is Arrhenius acid as well as Bronsted acid.

Assertion (A): The Heat of ionisation of water is equal to the heat of neutralistion of a strong acid with a strong base. Reason (R ) : Water ionises to a very small extent while H^(o+) ions from from an acid combine very rapidly with overset(Theta)OH from a base to form H_(2)O .

Why is benzoic acid less soluble in water than acetic acid?
