Is melting of ice a chemical change ?

No , melting of ice will not be a chemical change as it simply involves the change in the state of water. But during this change the colour, odour, taste , chemical or molecular formula will remain the same . And these all are the indications of physical change only.

Is an alloy a pure substance or a mixture?

This question can be explained in the light of following concepts. In case of alloy the metals are mixed by melting them. The main point to note is that the proportion is not fixed in case of alloys. But in pure substances the proportion is fixed . And they make same kind of particles .Continue reading “Is an alloy a pure substance or a mixture?”

Why is an ionic bond not double or triple like a covalent bond?

To understand this we have to go in depth , that how the ionic bond is formed? Ionic bond is a bond basically formed due to strong electrostatic forces of attraction which is totally different from the covalent bond. Ionic bond is formed between atoms with very different ionisation energy and electron affinity. This situationContinue reading “Why is an ionic bond not double or triple like a covalent bond?”

Why the diastereomers of optically active compounds are optically inactive?

Firstly let us discuss what are optically active compounds? These are the compounds that rotate the plane of polarized light. Now Diastereomers are basically mirror images of two optically active compounds. They rotate the plane of polarized light, either to the left side or to the right. If they are present together, they cancel theContinue reading “Why the diastereomers of optically active compounds are optically inactive?”
