Which has higher melting point KCl or HCI?
Melting points: KCl: 770oC HCl: -114.22oC
Why the melting point of potassium fluoride is higher than the melting point of potassium iodide?
KF has small size than KCl. So the packing of atoms / ions in KF is more than that in KCl. So a larger energy is needed to separate the atoms from solid state to liquid state and hence KF has higher melting point than KCl.
How can you check the purity of Kcl?
If you melt the HCl, and it melts at the proper melting point for HCl, then it is a pure substance. If not, it has been mixed with something else, which has altered the purity of the HCl.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
Silicons melting point?
The melting point of silicon is 1414C.
Which has higher melting point KCl or HCI?
Melting points: KCl: 770oC HCl: -114.22oC
What is the balanced equation for heating potassium chloride?
There is no reaction (decomposition) when KCl is heated, other than the melting of KCl, above its melting point.

Why KCl or KF is added in the electrolysis of molten NaCl?
To decrease melting point of NaCl
Can potassium chloride andsodium chloride be separated by sublimation?
No, because neither of them sublimate at 760 torr (1 atm). They melt. You could separate them by melting point, as NaCl has a melting point of 801ºC, but KCl has a melting point of 770ºC.
What is Iodine solid wax brass argon KCl ranked from lowest melting point to highest?
1. Argon 2. Solid Wax (C20H42) 3. Iodine 4. KCl 5. Brass

Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
melting point
The temperature at which a solid melts is called?
melting point
What is difference between melting point and drop melting point?
No basic Difference between melting point and Drop point.
What becomes solid above the melting point?
assuming it is its own melting point NOTHING which is why its a MELTING point
