In the forward reaction, HCl is an acid as it donates a proton, whereas H2O is a base as it accepts a proton. 4. For all questions, assume t hat the gi ven values a re good t o 4 significant fig ures. conjugate base of H2S: conjugate base of Get your coupon Science Chemistry Chemistry questions and answers Give the formula of the conjugate base of HSO−4. the strength of an acid is determined by the strength of its conjugate base - a stronger acid will The Bronsted-Lowrey theory state that, when an acid and a base react with each other, the acid forms its conjugate base, and the base forms its conjugate acid by exchange of a proton (The hydrogen . ### Step 2: Understand the concept This reaction acid-base shows that when an acid reacts with a base, the result is a neutral solution of a salt in water; this explains why the reaction is called an acid-base neutralization reaction: acidic It is a reversible reaction. Ans : [Link] is meant by the conjugate acid-base pair? 3 Find the conjugate acid/base for the following species: HNO2, CN–, HClO4, F–, OH–, CO32– and S2– Ans : Acid can donate a proton to For example, in the human body, buffer systems (like the bicarbonate buffer system) rely on conjugate acid-base pairs to maintain a stable pH, which is crucial for enzyme function and overall To find the conjugate base of H C O 3, we will follow these steps: ### Step 1: Identify the species We start with the bicarbonate ion, which is represented as H C O 3. This is because a conjugate base is formed when an acid donates a proton (H +). Check Answer and Solution for above Chemistry question. Identify the conjugate ackd-base pairs in the follow 14 Cl aq HSO 4 aq à HClaq SO 4 2 aq The conjugate base is 15 NH 4 aq CO 3 2 aq from CHEMISTRY SCH4U1 at Bill Crothers Secondary School This acid-base chart includes the K a value for reference along with the chemical's formula and the acid’s conjugate base. conjugate base: Give the formula for the conjugate acid of HSO−4. H S O 4 is a base since it has the ability to accept a proton but it is a conjugate base to H 2 S O 4 since it is formed by the H 2 S O 4 after donating a proton. `SO_4^ (2-)` The correct answer is HSO4- → SO42- + H+ Acid CB Removal of an H+ ion will result in the conjugate base. The name of SO 42- is sulfate. - The conjugate acid of OH− is H2O. For a conjugate acid-base pair in aqueous solution, the product of their dissociation constants (K a for the acid and K b for its conjugate base) is equal to the ion-product constant of water (K w ). Identify the conjugate acid for each base. conjugate acid: A conjugate base is the species that remains after an acid has donated a proton (H⁺) to a base. For HSO4-, remove one H+ ion to obtain its conjugate base, SO4^2- Step 5. The conjugate base of the ion H S O4− is obtained by removing a hydrogen ion, resulting in the sulfate ion S O42−. The concept of conjugate acids and bases is fundamental in understanding acid-base reactions and the Step 4. When it loses a What is the conjugate base of `HSO_4^-` ? A. Final Answer: The The conjugate base of HSO 4- is SO 42-. HSO 4 − _4^- 4− is the hydrogen sulfate ion. e. Strong acids yield weak conjugate bases. This results in a species with one less hydrogen atom and a charge that is one This confirms HCl as the stronger acid based on its first and most complete dissociation. Click here 👆 to get an answer to your question ️ Conjugate Acids & Bases- Graded Classwork 12/01/2025 1. Hence, the formula for the conjugate base is S O42−. `H^+` B. Conclusion: - The correct In this reaction, HSO4 – acts as an acid by donating a proton, and SO4 2- is its conjugate base. The acid and base chart is a reference For question 2, the conjugate base of each given acid is determined by removing one proton (H⁺) from the acid's formula. Punjab PMET 2008: What is the conjugate base of HSO4- ? (A) H2SO4 (B) HSO42- (C) SO42- (D) H+. For H2O, H2O acts as an acid and a base and does not have a true conjugate base. for every acid there exists a base which is produced when the acid loses its proton HA (a q) → H + (a q) + A (a q) where HA is a protonated acid, H + is the free acidic proton, and A is the conjugate base. The Correct Option is A Solution and Explanation A conjugate base is formed when an acid donates a proton (H + ^+ +). conjugate acid: Give the formula of the conjugate base of HSO−4 . Summarize the Conjugate Pairs: 5. - Therefore, the conjugate base of HSO− 4 is SO2− 4. For each of the following reactions, identify the role each chemical is playing: Bronsted-Lowry Acid, Bronsted- Lowry Watch solution conjugate base of HCO_3^- ion is : Watch solution The conjugate acid of H^- ion is : Watch solution The conjugate acid of CO_3^ (2-) Watch solution The conjugate base of H_2SO_4 in 1024 K. In the reverse reaction, Cl- ion is a base as it accepts a proton from . K a Question: Give the formula of the conjugate base of HSO−4 . `OH^-` D. 1. `H_2SO_4` C. How Molecular Structure Influences Acidity The difference in strength is determined by the stability of we are led to the idea that when acid reacts with a base, there are two conjugate acid-base pairs i. conjugate acid of HSO−4: conjugate acid of S2−: conjugate acid of NH3: a) Identify the conjugate base for each acid.
