it means that the acid or the base doesn't completely dissociate when placed in water. Let's take a weak acid. HNO2. When placed in water, not all of the HNO2 molecules will break apart. The ions in the solution will be H+, NO2-, and HNO2. Because there are less ions in the solution, the acid/base is weak. Not all of the HNO2 will break apart! A strong acid will completely dissociate. That means if you place HCl in water, the ions will be H+, and Cl-, NO HCl. This is because once they break apart, the chlorine will stay apart from the hydrogen. This leaves many ions in the solution, making the acid/base strong.
What else can I help you with?
Is the conjugate of a strong base is a weak acid?
NaHCO3 is a weak base, with a conjugate acid of H2CO3+.
Is CHOOH a weak acid or a weak base?
The formic acid is a weak acid.
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
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.
What is the relationship between a weak acid and its conjugate base in a chemical reaction?
In a chemical reaction, a weak acid and its conjugate base are related as a pair. When the weak acid donates a proton, it forms its conjugate base. The conjugate base can then accept a proton to reform the weak acid. They exist in equilibrium, with the weak acid and its conjugate base acting as partners in the reaction.
