Is NaCl or NaBr stronger?
The attractive forces between a pair of oppositely charged ions is referred to as “lattice energy”. Cl is a smaller atom than Br; therefore, one would expect a stronger lattice energy within NaCl than NaBr thereby making NaBr more soluble.
Which is stronger NaF or NaCl?
NaF is more stable than NaCl. These are ionic compounds and in these, strength is directly related to the lattice energy which is dependent on the charges and ionic sizes.So, greater is the negative charge of Fluorine and smaller ionic size compared to Chlorine, which leads to stronger bonds.
Which bond would you expect to be the strongest based on coulombic forces?
According to Coulomb’s law, as the charges of the ions involved increase, the force between the charges increases. Therefore, we would expect BeS to have the strongest bond, because the ions have a charge of +2 and -2.
Why is sodium bromide stronger than sodium iodide?
Since Br is more readily reactive with Na than I, the bond between Na and Br is stronger than the bond between Na and I. Thus, the boiling point of NaBr is higher than the boiling point of NaI . To check, the boiling point of sodium bromide (NaBr) is 1,396oC, while the boiling point of sodium iodide (NaI) is 1,304oC.
How do you know which ionic compound has the highest melting point?
In general, the greater the charge, the greater the electrostatic attraction, the stronger the ionic bond, the higher the melting point.
When sodium and chlorine react energy is?
So, an ionic bond is formed between sodium and chlorine. The formation of ionic bonds is exothermic.
Which ionic compound has the highest melting point?
Explanation: Ionic compounds have higher melting points than covalent compounds with small molecules. So the answer must be NaCl or MgO .
Which compounds have the strongest ionic bonds?
Answer: The combination of Mg2+ and O2- has the strongest ionic bond because it has high lattice energy among all the given options.
Why is AlCl3 a more powerful coagulating agent than NaCl?
By hardly schulze rule, for a negatively charged sol, positively charged ion with higher oxidation state is a better coagulating agent. Since AlCl3 forms Al3+ ion and NaCl forms Na+1 only, AlCl3 is a better coagulating agent.
