What else can I help you with?
What is the color of potassium chlorate?
Potassium chlorate is a white or colorless crystalline solid.
What is the colour of potassium nitrate solution?
Due to the potassium ion in potassium nitrate, any firework composition made with potassium nitrate would sport a purple/violet color, unless a strong colorant compound like strontium chloride is added to the composition.
What is the colour of potassium permanganate solution?
The color is a very strong and deep purple color when concentrated and pinkish in very low concentration.
What color is K2SO4 solution?
A solution of K2SO4, which is potassium sulfate, is typically colorless.
How a crystal potassium permanganate in a beaker change colour in water within minutes?
When potassium permanganate crystals are placed in water, they dissolve and release potassium and permanganate ions. These ions react with water molecules to form manganese dioxide, which gives the solution a pink or purple color. The rapid color change is due to the quick reaction of the ions with the water, causing the solution to turn vividly colored within minutes.
What is the color of potassium chlorate?
Potassium chlorate is a white or colorless crystalline solid.
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.

A test that can be used to determine whether a solution has potassium sulfate?
To determine if a solution contains potassium sulfate, you can perform a flame test. When a sample of the solution is heated in a flame, the potassium ions will emit a lilac flame color, which is characteristic of potassium compounds. This can help confirm the presence of potassium sulfate in the solution.
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.
When potassium iodide reactsa with potassium bromide in the presence of methylene what is the color change?
The reaction between potassium iodide and potassium bromide in the presence of methylene blue will result in the formation of elemental iodine (I2) which imparts a purple color to the solution. Initially, the reaction mixture will be colorless, but as iodine forms, the solution will turn purple.
What is the color of Potassium oxide?
When freshly cut it is silvery in colour but it quickly tarnished as it reacts with oxygen in the air. all alkali metals give characteristic flame colour wich are used to identify them potassium has the colour LILAC
What color is Lugol's solution prior to changing color?
Lugol's solution is a solution of iodine (1-5%) and potassium iodide in water. So the solution should have the pale color of iodine and the color should be pale (light) brown.
What is the color of potassium hydroxide?
In solution it is a colourless oily liquid As a solid it is a white flaky solid.
