The conjugate acid of HPO42- is H2PO4 H3PO4 PO43- PO42? The concept used to solve this problem is based on the conjugate acid and conjugate base. The conjugate acid base pair differs by one proton.
Explanation: The conjugate base of H3PO4 , phosphoric acid, is H2PO−4 .
Likewise, what is the conjugate base of the Bronsted Lowry acid hpo4 2 -? Hence an acid donates a proton to form it’s corresponding conjugate base while a base accepts a proton to form it’s corresponding conjugate acid. From Bronsted Lowry theory , we can conclude that the conjugate base of HPO4^-2 is PO4^-3.
Likewise, people ask, what is the conjugate acid of hpo2 − 4?
Table of acids and their conjugate bases
| Acid | Conjugate base |
|---|---|
| H2S Hydrosulfuric acid | HS− Hydrogen sulfide ion |
| H2PO − 4 Dihydrogen phosphate ion | HPO 2− 4 Hydrogen phosphate ion |
| NH + 4 Ammonium ion | NH3 Ammonia |
| H2O Water (pH=7) | OH− Hydroxide ion |
Is HClO a strong acid?
Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. any acid that is not one of the seven strong is a weak acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.)
Is nh4+ an acid or base?
NH4+, aka ammonium ion, is for all practical purposes an acid. It readily “gives off” a proton in the form of h+. NH4+ is the conjugate acid of the base, NH3, aka ammonia. Basically, NH4 + H2O -> NH3 + H3O .
Is h3po4 an acid or base?
Strong and Weak Acids and Acid Ionization Constant Acid Conjugate Base H2SO4 (sulfuric acid) HSO4− (hydrogen sulfate ion) HNO3 (nitric acid) NO3− (nitrate ion) Weak Acids H3PO4 (phosphoric acid) H2PO4− (dihydrogen phosphate ion)
Is hpo42 a strong acid?
It is a very weak acid. The pHa = 12.66; i.e. at this pH 50% is HPO4(-2) and 50% is PO4(-3).
What is the conjugate base of HCl?
HCl is a strong acid. When it donates a proton, a Cl– ion is produced, and so Cl– is the conjugate base.
What is the conjugate base for the acid HBr?
The HBr is a Brønsted acid, and the water is a Brønsted base. In the Brønsted-Lowry theory, a conjugate base is whatever is left over after the proton has left. Thus, HBr lost a proton to become Br?, so Br? is the conjugate base of HBr.
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.
Is water a base?
Water acts as an acid (donates H+) when it reacts with a stronger base, say sodium hydroxide. Water acts as a base (accepts H+) when it reacts with a stronger acid, say hydrochloric acid. If the medium is water, water, having a pH of 7, is considered neutral.
Is hpo4 amphoteric?
Both H2O and HPO4^2- are amphoteric.
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.
What is the conjugate acid for HS?
1 Answer. Al E. Hydrosulfuric acid is the conjugate acid of the hydrogen sulfite ion it dissociates into in solution.
What is the conjugate base of h3o+?
Water is the species accepting the proton, to form the hydronium ion, H3O+, making it the base. The F- (aq) is called the conjugate base of HF. It can gain a proton in the reverse reaction. H3O+ is the conjugate acid of H2O, since it can lose a proton in the reverse reaction.
What is hpo4?
The compound ion HPO4 is called hydrogen phosphate. The ion hydrogen phosphate carries a charge of -2 and is a salt of phosphoric acid through its conjugate base of dihydrogen phosphate. Hydrogen phosphate is formed when phosphoric acid loses two protons through a chemical reaction.
