Potassium sulfide (K₂S) has a higher boiling point than water (H₂O). While water has strong hydrogen bonding that contributes to its boiling point of 100°C, potassium sulfide is an ionic compound with strong electrostatic forces between its ions, resulting in a much higher boiling point around 840°C. Thus, the ionic nature of potassium sulfide leads to a significantly higher boiling point compared to water.
What else can I help you with?
Does potassium sulfide have a higher boiling point than water?
Yes, potassium sulfide (K₂S) has a higher boiling point than water. Potassium sulfide is an ionic compound, which typically exhibits strong electrostatic forces between its ions, resulting in higher boiling points. In contrast, water, while it has hydrogen bonding, has a lower boiling point (100°C) compared to potassium sulfide, which boils at approximately 840°C.
What is the boiling point for iron sulfide?
The boiling point of iron sulfide (FeS) is approximately 1,404 degrees Celsius (2,559 degrees Fahrenheit).
Why boiling point of calcium is higher than that of potassium?
The boiling point of calcium is higher than that of potassium primarily due to the stronger metallic bonding in calcium. Calcium, being a divalent metal, has two valence electrons that contribute to stronger metallic bonds, while potassium, a monovalent metal, has only one. This results in a higher energy requirement to break the bonds in calcium, leading to a higher boiling point compared to potassium. Additionally, calcium's smaller atomic size and higher charge density further enhance its bonding strength.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
Which has a higher boiling point 0.50 NaCl or 0.50 MgCl2?
The magnesium chloride solution has a higher boiling point.
Does potassium sulfide have a higher boiling point than water?
Yes, potassium sulfide (K₂S) has a higher boiling point than water. Potassium sulfide is an ionic compound, which typically exhibits strong electrostatic forces between its ions, resulting in higher boiling points. In contrast, water, while it has hydrogen bonding, has a lower boiling point (100°C) compared to potassium sulfide, which boils at approximately 840°C.
Why does potassium chloride have a higher boiling point?
Potassium chloride has a higher boiling point than potassium because it is a compound made up of both potassium and chlorine ions, leading to stronger attraction forces between the molecules. This stronger attraction requires more energy to break the bonds between the ions, resulting in a higher boiling point compared to pure potassium.
Why boiling point of potassium higher than its melting point?
The boiling point of an element is often higher than its melting point because it takes more energy to separate the molecules in a liquid and turn them into a gas. In the case of potassium, the boiling point is higher than the melting point because the forces holding the potassium atoms together in a liquid state are stronger than in a solid state.
What is the boiling point for iron sulfide?
The boiling point of iron sulfide (FeS) is approximately 1,404 degrees Celsius (2,559 degrees Fahrenheit).
What is the boiling point of potassuim?
The boiling point of potassium is 759 °C.
Why boiling point of calcium is higher than that of potassium?

Why is the boiling point of water greater than hydrogen sulfide?
The boiling point of a substance is determined by the strength of the intermolecular forces between its molecules. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point in water.
Why's the boiling point of hydrogen sulfide slightly higher than hydrogen selenide?
Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water.
What has the lowest boiling pt KCl or KI?
The boiling point of potassium iodide is 1 330 0C. The boiling point of potassium chloride is 1 420 0C.
What has a higher boiling point water or KI?
Potassium iodide has a higher boiling point because it is ionically bonded while water is polar covalent (with hydrogen bonds). The ionic bonds on KI are stronger than the bonds of water. This means that the molecules are "stuck" to each other stronger than water's molecules. Then it would take more energy (heat) to "unstick" them to change its state of matter, resulting in a higher boiling point.
