If an acid is made from the anion SO42-, what would it's formula be?

KatRina [158]

<u>Answer:</u> The chemical formula of the compound formed is $H_2SO_4$

<u>Explanation:</u>

Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.

$HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)$

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

We are given:

An anion having chemical formula $SO_4^{2-}$ named as sulfate ion

This will combine with 2 hydrogen ions to form a neutral compound. The neutral compound formed is sulfuric acid.

Hence, the chemical formula of the compound formed is $H_2SO_4$

Calculate the ph of a mixture that contains 0.18 m of hno3 and 0.24 m of hbro

Kobotan [32]

HNO3 is a strong acid while HBrO is weak acid.
Therefore we ignore the presence of the weak acid such that we consider the pH of the strong acid.
Therefore; since pH= - log (H+)
Hence pH= -log 0.18
= 0.745
Thus the pH of the mixture is 0.745
