Write the formula of the conjugate base for acid H3PO4 and what is the name of the base

Write the formula of the conjugate base for acid H3O+ and what is the name of the base
..........and how can i tell how to get it? i am lost

Write the ionization of H3PO4.

H3PO4 + H2O ==> H3O^+ + H2PO4^-

So H3PO4, phosphoric acid, lost a proton to form H2PO4^- so H2PO4^- is the conjugate base of H3PO4, the acid. H3PO4/H2PO4^- is the acid/conjugate base pair. H2O gained a proton to form H3O^+; therefore, H2O is the base and H3O^+ is its conjugate acid. The H2PO4^- ion is named dihydrogen phosphate ion.

To find the formula of the conjugate base for an acid, you need to understand the concept of acid-base reactions. In an acid-base reaction, an acid donates a proton (H+) to a base, forming a conjugate base and a conjugate acid.

Here is how you can find the formula of the conjugate base for a given acid:

1. Identify the acid molecule: In this case, the given acid molecules are H3PO4 and H3O+.

2. Remove a proton (H+) from the acid molecule: The conjugate base is formed by removing a hydrogen ion (proton) from the acid molecule.

Formula of the conjugate base for H3PO4:
The acid H3PO4 can lose one proton (H+), resulting in the formation of the conjugate base PO4^3-. So, the formula of the conjugate base for H3PO4 is PO4^3-.

Name of the base for H3PO4:
The conjugate base is derived from an acid. In this case, the acid H3PO4 is called phosphoric acid. The conjugate base PO4^3- is known as the phosphate ion.

Formula of the conjugate base for H3O+:
The acid H3O+ already has a proton (H+), so it cannot lose another proton to form a conjugate base. Therefore, the conjugate base for H3O+ is OH- (hydroxide ion).

Name of the base for H3O+:
H3O+ is formed by the combination of H2O (water) and an additional H+ ion. When H3O+ loses its H+ ion, it forms the hydroxide ion (OH-), which is the conjugate base. The hydroxide ion is simply referred to as the hydroxide ion.

Remember, to find the formula of the conjugate base, you need to remove a proton from the acid molecule, and the resulting species is the conjugate base. The name of the base is derived from the name of the acid, with some changes according to the specific rules of nomenclature.

To determine the formula of the conjugate base for an acid, you need to identify the acid's formula and remove one proton (H+) from it. Here are the steps to find the conjugate base:

1. For the acid H3PO4 (phosphoric acid), remove one proton (H+) from the formula:
H3PO4 - H+ = H2PO4^-

The formula for the conjugate base of H3PO4 is H2PO4^-. The name of this base is dihydrogen phosphate.

2. For the acid H3O+ (hydronium ion), remove one proton (H+) from the formula:
H3O+ - H+ = H2O

The formula for the conjugate base of H3O+ is H2O. The name of this base is water.

To determine the conjugate base, you can identify the acid and remove one proton to obtain the conjugate base. Note that the conjugate base has one less positive charge (proton) compared to the acid.
