Answer: 1) only a salt and water
An acid and base reacts together to undergo neutralization to form salt and water.
where HCl is an acid and NaOH is a base to form salt (NaCl) and water .
Answer: 2) The formula of the hydrogen ion is often written as .
All acids dissociate in water to give ions.
Answer: 3) Arrhenius acids are substances that ionizes to yield protons in aqueous solution.
Arrhenius bases are substance that ionizes to yield hydroxide ions in aqueous solution.
Answer: 4) A conjugate acid base pair transfers hydrogen ion.
Here accepts a proton and thus act as a base and the corresponding
is its conjugate acid.
Answer: 5) Bronsted Lowry acid is a substance that donates protons. Bronsted Lowry base is a substance that accepts protons.
and
is a acid which accepts proton and thus acts as base to form conjugate acid
.
- The oxidation state of the manganese atom
changes from +7 as in
to +4 as in

- There are one

- Reducing each
- Similarly, the oxidation state of the chlorine atom
changes from -1 as in
to 0 as in
.
- It takes two
- Oxidizing every two
Three molecules contain six chlorine atoms. Three
would thus correspond to six
ions.
Combining six , two
ions, three
ions, and two
would balance the changes in oxidation state.
(NOT BALANCED)
Still, the product side lacks four oxygen atoms.
- In an acidic environment, oxygen atoms would combine with protons to produce water.
- In a basic environment (like this one,) there are nearly no protons for oxygen atoms to combine with. Oxygen atoms will likely combine with water to produce hydroxide ions.
Each oxygen atom combine with a water molecule to produce two hydroxide ions. Adding four water molecules and eight hydroxide ions would balance the equation.
