What is the formula for NH4 and O?
NH₄⁺
Is NH4 an acid or base?
Weak base dissociation eg NH3 NH3 is a weak base and dissociates partially in solution (as indicated with reversible arrow) to form OH- and NH4+ ions. Since this is a reversible process, NH4+ can donate H+ to form back NH3. Therefore the nature of NH4+ is acidic and we call NH4+ the conjugate acid of NH3.
Why is BaCl2 neutral?
Aqueous solutions of barium chloride have neutral pH values since they contain the cation of a strong base and the anion of a strong acid.
Is BaCl2 a pH?
BaCl2 crystallizes in two forms (polymorphs). In aqueous solution BaCl2 behaves as a simple salt; in water it is a 1:2 electrolyte and the solution exhibits a neutral pH.
Why BaCl2 has high boiling point?
Since both the salt solution have same concentration, therefore the salt which gives maximum number of ions will show higher boiling point. NaCl dissociate to give two ions while BaCl. Hence BaCl2 posses high boiling point. Bacl2 will have higher boiling point as boiling point is a colligative property .
Which solution has highest boiling point?
and “1%NaCl in water” gives two ions so it will have highest boiling point.
Which solution has maximum boiling point?
Thus, Na3PO4 has the highest boiling point.
Which has high melting point LICL or BeCl2?
becl2 has the highest boiling point. Explanation: This is an ionic compound. And according to the feature of e ionic compounds they have high melting points as they are ionically charged particle,they need more heat.
Which has highest melting point LICL?
In BeCl2 has the highest melting point due to ionic bond.
What is the melting point of LICL?
605 °C
Which is more ionic BeCl2 or BaCl2?
“BeCl2 is largely covalent but BaCl2 is largely ionic in nature”-explain on the basis of polarization.
Why is BeCl2 covalent and BaCl2 ionic?
Therefore cannot form ionic bond. Due to small size and high charge density Be, its polarizing power is maximum, since Be+2 ion essentially pull the electrons cloud from Cl- , such that the electrons pair are effectively shared. This give covalent character to BeCl2.
Which is more ionic MgCl2 or BaCl2?
The cation with the smallest electronegativity is Barium, so BaCl2 has the largest difference in electronegativity; which also means that it has the highest ionic character. So, in the given set, the order of increasing ionic character is as follows: BeCl2<MgCl2<CaCl2<BaCl2 .
