This really depends. When a strong base reacts with a strong acid, a neutralization reaction occurs, making H2O and neutralizing the pH of the substance. However, when a strong base reacts with a normal acid, nothing is always produced, and the solution will be slightly less basic.
Answer: c. +4
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.




Here manganese is having an oxidation state of +4 called as cation and oxygen forms an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged to give
which written in simplest whole number ratios to give neutral 
Answer:
Key Points. Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal.
