What combinations of compounds will make a buffer when mixed?
In order to have an effective buffer, one needs to have a weak acid or a weak base, and the salt (conjugate) of that weak acid or weak base. Examples would be :weak acid/conjugate base: acetic acid/sodium acetateweak base/conjugate acid: ammonia/ammonium chloride
Is HF and acid base or salt?
HF is a weak acid.
Why the weak acid cannot be used as titrant?
If you are titrating a base, using a weak acid as titrant would lead to the formation of a buffer as you added the weak acid. The weak acid would react with the base to form the salt of the weak acid + water, and this would buffer any changes in pH, thus making the titration meaningless.
What kind of base and acid is carbon dioxide weak or strong?
Dissolved carbon dioxide in water (carbonic acid) is weak acid.
Is phenolphthaleine an acid or base?
I think it is neutral
Is CHOOH a salt?
No, CHOOH is not a salt. CHOOH typically represents a functional group known as a hydroxyl group, which consists of an oxygen and a hydrogen atom bonded to a carbon atom. Salts are formed when a metal cation replaces the hydrogen atom in an acid group.
Is the conjugate of a strong base is a weak acid?
No, the conjugate of a strong base is a weak acid. The conjugate base of a strong acid is weak, while the conjugate acid of a strong base is weak.

Which statement always accurately describes acids and bases a the conjugate base of a weak acid is a strong base b the conjugate acid of a weak base is a weak acid c strong acids and st?
b) The conjugate acid of a weak base is a weak acid. When a base accepts a proton to form its conjugate acid, it tends to be a weak acid because it does not easily donate a proton back. This relationship is governed by the principles of acid-base equilibrium.
Is hcoo-a weak base?
HCOO- is the conjugate base of formic acid (HCOOH) which is a weak acid. Therefore, HCOO- is a weak base.
A solution containing either a weak acid or a weak acid its saltor a weak base and its salt?
A solution containing a weak acid and its salt will act as a buffer, maintaining the pH by neutralizing added acid or base. Similarly, a weak base and its salt can also function as a buffer. Weak acid-weak base buffer systems are commonly used in chemical laboratories and biological systems to control pH fluctuations.
Is C2H3O2 an strong or weak acid or base?
CH3COOH is a acid. It is a weak acid.
Is HNO2 a weak base?
No, HNO2 is a weak acid, not a weak base. It is a weak acid because it only partially ionizes in water to release H+ ions.
Is HCO3 a weak or strong acid?
HCO3 is not an acid, but a base. It is the conjugate base of the weak acid H2CO3 (carbonic acid). In water, it can act as a weak base by accepting a proton to form H2CO3.
Is C2H4O2 weak or strong?
it is a non electrolyte C2H5OH is not a base, its an alcohol, ETHYL ALCOHOL so its just an alcohol
Is NaCl a weak acid?
No, NaCl is neither an acid, weak acid, or a (weak) base. It is considered a salt.
Is CHOOH an acid?
Yes, CHOOH is methanoic acid - it is an organic acid because it contains the "COOH"functional group. The carbon atom has one bond with the hydrogen atom, and one bond with the OH molecule, and finally a double bond with the oxygen.
