Is PO4 3 covalent or ionic?
“PO4” isn’t a compound, it is the phosphate ion, and has an oxidation state of -3. The bonds in PO4^3- have high covalent character… 32% ionic character and 68% covalent character. “PO4” isn’t a compound, it is the phosphate ion, and has an oxidation state of -3.
Why does PO4 3 have a double bond?
Since Phosphorus is in the third period it has access to the d orbital allowing it to be an exception to the octet rule. By double bonding to 1 of the oxygens, there is no change in the amount of valence electrons being used, but there is more stability in the formal charge.
What kind of bond is MgBr2?
These are Magnesium bromide is MgBr2. “ionic compounds.” When atoms join together, they form either molecules or ionic compounds, depending on whether they are joined by covalent bonds or ionic bonds. When atoms join together by covalent bonds, they form “molecules”.

Is NH4Cl a strong acid?
Ammonium chloride (chemical formula NH4Cl) is an acidic salt since it is a salt of a strong acid, namely hydrochloric acid, and a weak base, namely ammonium hydroxide.
Which is more acidic NaCl or NH4Cl?
Answer. NH4Cl, when dissolved in water, shows a different behavior. As mentioned in the other answer, NH4Cl is an “acidic” salt, formed by the neutralization of a strong acid (HCl) with a weak base (NH3). Therefore, when the salt is completely dissociated in an aqueous solution, it forms NH4+ and Cl- ions.
