What is the melting point of sodium bromide?
Bromine (Br): Melting point: - 7,2 0C Boiling point: + 58,8 0C
What is the Chemical formula for sodium bromide gas?
NaBr is sodium bromide but it is an ionic solid with a high melting point and extremely unlikely to be a gas.
Why is benzene formed during Grignard reactions using phenylmagnesium bromide?
Grignard reactions must be carried out in an anhydrous environment in an anhydrous solvent (e.g. anhydrous ether). Why? Grignard reagents behave essentially as a carbanion, and are extremely reactive. Therefore they cannot be carried out while acidic hydrogens, or other positive reactive centers are present (carbonyl compounds such as acetone) in the reaction mixture because there is no way to stop the Grignard from reacting with these other compounds rather than the desired reactant. If phenylmagnesium bromide were prepared, and ANY water was present in the reaction mixture phenylmagnesium bromide would not hesitate to react with water--stealing one of its hydrogens. This hydrogen would therefore replace the attached --MgBr to form benzene.
Why is KBr liquid at room temperature?
KBr (potassium bromide) is a salt that has a relatively low melting point of 734 degrees Celsius. At room temperature and pressure, it remains in a solid state. To become a liquid, KBr must be heated above its melting point to transform into a liquid form.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
What is the melting point of iron bromide?
Iron bromide does not have a distinct melting point since it is typically found as a mixture of different iron bromide compounds. The melting point can vary based on the specific compound in the mixture.
What is the melting point of magnesium bromide?
Melting point of the anhydrous MgBr2 is 711°C.
What is the melting point of potassium bromide?
The melting point of potassium bromide is 734 degrees Celsius.
Does strontium bromide have a high melting point?
Yes
What is the melting point of sodium bromide?
Bromine (Br): Melting point: - 7,2 0C Boiling point: + 58,8 0C
Why strontium bromide has high melting point?
Strontium bromide has a high melting point due to the strong ionic bonds between the strontium cations and bromide anions in its crystal lattice structure. These bonds require a significant amount of energy to break, resulting in a high melting point.
Why does sodium bromide have a high melting point?
Sodium bromide has a high melting point because of the strong electrostatic forces of attraction between the positively charged sodium ions and negatively charged bromide ions in the crystal lattice. These forces require a significant amount of energy to overcome, resulting in a high melting point for the compound.

Which of following solids would hae higher melting point AlO3 vs NaBr?
Aluminum oxide (Al2O3) would have a higher melting point than sodium bromide (NaBr). This is because aluminum and oxygen ions in Al2O3 are more strongly bonded through covalent bonds, while sodium and bromide ions in NaBr are held together by weaker ionic bonds. Stronger bonding requires more energy to break, resulting in a higher melting point.

What is the boiling and melting point of HBR?
Hydrobromic Acid (HBr) Melting point: -11 °C (47-49% w/w aq.) Boiling point: 122 °C at 700 mmHg (47-49% w/w aq.)
