1 Answer. Al E. Hydrosulfuric acid is the conjugate acid of the hydrogen sulfite ion it dissociates into in solution.
You are watching: Is hs- an acid or base
Moreover, for what acid is HS − the conjugate base?
In summary, this can be represented as the following chemical reaction: Acid + Base ⇌ Conjugate Base + Conjugate Acid. Table of acids and their conjugate bases.
|H2S Hydrosulfuric acid||HS− Hydrogen sulfide ion|
Secondly, what does conjugate acid mean? In other words, a conjugate acid is the acid member, HX, of a pair of compounds that differ from each other by gain or loss of a proton.
Likewise, people ask, what is the conjugate base for HS?
The conjugate base of HS– is S2-. HS– loses a proton (H+). Notice that the proton has a positive charge.
What is the conjugate acid of po3 4?
Answer and Explanation: The conjugate acid of PO3 –4 is HPO3 -3. The conjugate acid of a substance can be determined by adding a hydrogen ion to the substance.

Is HCl a strong acid?
A strong acid is an acid which is completely ionized in an aqueous solution. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water. Because HCl is a strong acid, its conjugate base (Cl−) is extremely weak.
Is hno3 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). They simply do not ionize completely whereas a strong acid or base does. That means for a solution of 0.1 M HCl compared to 0.1 M HF the HCl solution will contain more H+ and be more acidic.
Is ch3ch2oh a Bronsted Lowry acid?
CH3CH2OH Can Be A Bronsted–Lowry Acid. C) CH3 CH2OH Can Be A Bronsted–Lowry Acid, CH3CH2NH2 Can Be A Bronsted–Lowry Base, And CH3CH2OH Can Be A Lewis Base.
What is Ka chemistry?
An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction. known as dissociation in the context of acid–base reactions.
Is HS an acid or base?
The HS– gains the H+ ion, so it is the Brønsted-Lowry base. c. The HS– loses an H+ ion, so it is the Brønsted-Lowry acid.
Why do buffer solutions form?
A buffer solution is one which resists changes in pH when small quantities of an acid or an alkali are added to it. An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts – often a sodium salt.
What is the formula for the conjugate base of h2s?
Answer and Explanation:
The conjugate base of H2 S is HS-1. The removal of a hydrogen ion is the equivalent of removing a proton.
Is ch3coo a conjugate acid or base?
CH3COOH is a weak acid and dissociates partially in solution (as indicated with reversible arrow) to form H+ and CH3COO- ions. Since this is a reversible process, CH3COO- can accept H+ to form back CH3COOH. Therefore the nature of CH3COO- is basic and we call CH3COO- the conjugate base of CH3COOH.
What is the conjugate acid of s2 -?
The conjugate acid of S2− S 2 − is HS− H S − . To determine the conjugate acid, you add a proton. A proton is an H+ H + , so to determine the conjugate acid, you will add a H and a +1 to the charge of the base.
What is the conjugate base of h2po4 -?
Answer and Explanation:
The conjugate base of H2 PO4 – is HPO4 -2. The removal of a proton (H+1) from a conjugate acid gives us its conjugate base.
What is the conjugate base of ch3oh?
There are lone pairs on O atom in CH3OH. For which CH3OH act as base and CH3OH2+ is the conjugate acid. Addition of H+ to the conjugate base will give conjugate acid.
What is the conjugate base of ch3nh2?
In the above reaction, methylamine accepts a proton from water and is thereby a Bronsted base. For the reverse reaction, the opposite is true, as CH3NH3+ donates a proton to hydroxide, classifying it as a Bronsted acid. Therefore, CH3NH3+ is the conjugate of methylamine.
What is the conjugate base of hno2?
The “Conjugate Base” is the Chloride anion (Cl−) which has the potential of functioning as a proton acceptor. However neither the H−OHorCl− have strong enough electrostatic properties to interact in a proton transfer process of transferring the Hydrogen back to the Hydroxide ion.
What is the conjugate base of h2co3?
Answer and Explanation:
The conjugate base of H2 CO3 is HCO3 -. To determine the conjugate base, remove a proton (H+) from the acid.
Is HCl a Bronsted Lowry acid?
The Brønsted–Lowry Theory of Acids and Bases
Therefore, HCl is a Brønsted–Lowry acid (donates a proton) while the ammonia is a Brønsted–Lowry base (accepts a proton). Also, Cl- is called the conjugate base of the acid HCl and NH4+ is called the conjugate acid of the base NH3.
Is NaOH an acid or base?
NaOH is a base because when dissolved in water it dissociates into Na+ and OH- ions. It is the OH- (hydroxyl ion) which makes NaOH a base. In classical term a base is defined as a compound which reacts with an acid to form salt and water as depicted by the following equation.
What is a conjugate acid Example?
A conjugate acid is the product that is different from a base by one proton. Examples of conjugate acids include water (base) reacting with an acid to form the hydronium ion (conjugate acid), and ammonia (base) reacting with an acid to form the ammonium ion (conjugate acid).
