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.
Is phenolphthaleine an acid or base?
I think it is neutral
What kind of base and acid is carbon dioxide weak or strong?
Dissolved carbon dioxide in water (carbonic acid) is weak acid.
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 HCN an acid or base?
HCN is a weak acid. It partially dissociates in water to form H+ ions and CN- ions.
