Answer 2

1) Chemical Formula: KMn04

Molar Mass: 158.034 g/mol

Appearance: Purplish-Bronze-Gray-Needles Magenta-Rose in Solution

Odor: Odorless

2) Appearance: Gray-White (Anhydrous)

Blue (Pentahydrate)

Density: 3.60 g/cm³ (anhydrous)

2.286 g/cm³ (Pentahydrate)

Melting Point: 110° C (230 °F; 383 K)

Decomposes (•5H2O) if

Pentahydrate <560 °C

Decomposes if anhydrous fully

decomposes at 590 °C

Boiling Point: Decomposes to cupric oxide at 650 °C
