Why does the purple colour of potassium maganate VII spread when crystal dissolves in water?
The purple color of potassium permanganate (KMnO4) spreads as the crystal dissolves in water because the compound is highly soluble in water and dissociates to form MnO4- ions. These ions impart a deep purple color to the solution due to the absorption of light in the visible spectrum. The spreading of the color occurs as the MnO4- ions disperse uniformly throughout the water.
What color flame is produced when potassium metal reacts with water?
When potassium metal reacts with water, it produces a lilac-colored flame. This flame color is a result of the energy released during the chemical reaction between potassium and water.
Why does the purple colour spread when a crystal of potassium permanganate is placed in water?
The purple color spreads when a crystal of potassium permanganate is placed in water due to the dissolution of potassium permanganate molecules in water. Potassium permanganate is a highly soluble compound, and its purple color comes from the permanganate ions in the crystal dispersing in the water. This dispersion allows the purple color to be visible throughout the water.
What is K2Cr307?
K2Cr2O7 is potassium dichromate, a commonly used oxidizing agent in chemical laboratories. It is orange in color and is soluble in water.
What would happen to large potassium magnate crystal in water after 5 minutes?
if the water is cold then the crystal will take time to dissolve as particles move slowly when in cold water. therefore, after 5 minutes it will still be the same or if its normal water it will start to diffuse slowly.
What happens to the colour of water when potassium permanganate is added?
When potassium permanganate is added to water, the water changes color to a pink or purple hue. This is because potassium permanganate is a strong oxidizing agent that reacts with organic compounds present in the water, causing the color change.
What would happen to large potassium magnate crystals in water after several hours?
If you think to potassium "permanganate" this compound can be decomposed under the influence of UV radiations.

Which metal reacts with water and burns with a lilac flame?
Potassium has a violet color in the flame test.

Is there a paint on product that changes color if exposed to water?
A paint that changes color with water is not expressly available. However, tea sensitive paint can be changed color with water of different temperatures!
What color is potassium carbonate?
In a flame test, potassium and its compounds emit a lilac color, which may be masked by the strong yellow emission of sodium if it is also present. Cobalt glass can be used to filter out the yellow sodium color. The potassium ion is colorless in water.
Why does the color of the potassium permanganate spread through the water?
When potassium permanganate is dissolved in water, it undergoes an exothermic reaction, which causes the rapid mixing and dispersion of the color throughout the solution. This process is driven by diffusion, as the particles of potassium permanganate move from regions of high concentration to low concentration, leading to the even spread of the color.
Why did the potassium permanganate colour move throughout the water?
The movement of the potassium permanganate color through the water is due to diffusion, a process where particles move from an area of high concentration to an area of low concentration to reach equilibrium. As the potassium permanganate particles spread out in the water, the color becomes more evenly distributed.
If beets soak in water overnight what color would the water be the next day?
it changes color because the color of the beets bleeds out and changes the color of the water?
What flower changes color accordingly to the color of the water?
white flower changes the colour according to the ink
