Hello there!
In this case, for the given chemical reaction:
We can see how there is one SO4 on the left and two on the right, thus, we add a 2 in front of H2SO4:
Next, since there are 8 atoms of hydrogen on the left and two on the right, we add a 4 in front of H2O to obtain:
Which is now balanced so the coefficients 2, 1, 1, 4.

Answer: hydroxide ions
Explanation:
According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion and a bases is a substance that ionizes in the water to give hydroxide ion .
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
As KOH can give hydroxide ions on dissociation , it is considered as arrhenius base.
