What are chemical properties of potassium?
Potassium metal is soft and white with a silvery lustre, has a low melting point, and is a good conductor of heat and electricity. Potassium imparts a lavender colour to a flame, and its vapour is green. It is the seventh most abundant element in Earth’s crust, constituting 2.6 percent of its mass.
Why potassium dichromate is Coloured?
The orange color of potassium dichromate is due to charge (electron) transfer from O2- ligands to the empty d orbitals of the central metal Cr6+, i.e. LMCT. This electronic transfer absorbs greenish blue light and leaves the complimentary orange light behind as the observed colour.
What are some of the side effects of potassium?
Some examples of potassium -related complications include life-threatening arrhythmia, neuromuscular dysfunction, diarrhea, nausea, and vomiting. Various pharmacological preparations have been formulated to replenish potassium.
