Answer:
Low melting point.
Explanation:
We cannot link the pH of a substance from it bonds directly.
Ionic compounds have strong ionic bonds but we cannot say that they will have high or low pH.
High conductivity is a feature of ionic compounds generally (also metals)
low melting point means the bonds are weak so they can be weak covalent bonds.
Low flammability is not related to bonding.
