When potassium is dropped into water colored with red litmus, it reacts vigorously, producing hydrogen gas and forming potassium hydroxide, which is a strong base. As the potassium hydroxide dissolves in water, it raises the pH of the solution, causing the red litmus paper to turn blue, indicating a shift to a basic environment. The reaction is exothermic and can be quite explosive, so it should be handled with caution.
What else can I help you with?
What oxide turns red litmus paper to blue when dissolved in water?
An oxide that turns red litmus paper blue when dissolved in water is typically a basic oxide, such as sodium oxide (Na2O) or potassium oxide (K2O). When these oxides dissolve in water, they form alkaline solutions, increasing the pH and causing the red litmus paper to change color to blue. This indicates the presence of a basic substance in the solution.
What color of litmus is water?
Litmus paper is typically blue. If water is tested with blue litmus paper and it turns red, it indicates that the water is acidic. However, if there is no color change, the water is neutral.
What element oxide turned red litmus paper to blue?
A basic element oxide, such as sodium oxide (Na2O) or potassium oxide (K2O), can turn red litmus paper blue. These oxides react with water to form alkaline solutions, raising the pH and causing the color change in litmus paper. The shift from red to blue indicates the presence of a basic substance.
What happen if the potassium permanganate solution drop to the water?
If potassium permanganate solution is dropped into water, it will dissolve and create a purple or pink solution. Potassium permanganate is a strong oxidizing agent and can be used for various applications such as disinfection and water treatment.
What observation will you make when red litmus paper and blue litmus paper are dipped in turns in distilled water?
When red litmus paper is dipped in distilled water, it will remain red, indicating that the water is neutral and does not change the acidity. Similarly, when blue litmus paper is dipped in the same distilled water, it will also remain blue. This observation confirms that distilled water has a neutral pH of around 7, which does not affect the litmus papers' color.
What will happen when paper is added to water?

What will happen if litmus paper is diped in lime water?
The litmus paper will turn blue if dipped in lime water, indicating that the lime water is basic. Lime water is a solution of calcium hydroxide, which is a strong base that can turn litmus paper blue.
Why does water become coloured when crystals of potassium permanganate are added to it?
Water turns colored when potassium permanganate is added because the potassium permanganate crystals dissolve, releasing the purple permanganate ion (MnO4-) into the water. The permanganate ion absorbs light in the visible spectrum, giving the water a pink or purple color.
How can you detect the alkali in the water at the end of the reaction of potassium with water?
One way to detect the alkali in water after the reaction of potassium is by using a pH indicator paper, which will turn a specific color in the presence of alkali. Another method is to perform a simple acid-base titration using an acid solution of known concentration and an indicator to determine the amount of alkali present in the water.
Which solution will not have any effect on both red litmus paper and blue litmus paper?
a)sulfur dioxide b)hydrogen chloride c)potassium sulfate d)slaked lime
What color of litmus is water?
Litmus paper is typically blue. If water is tested with blue litmus paper and it turns red, it indicates that the water is acidic. However, if there is no color change, the water is neutral.
What happens to litmus paper when water is added?
litmus paper nutral
What will happen if you mixed potassium with water?
i have no idea i was searching for it...i'm just playing around.
What will happen when potassium and water together what kind of changes?
When potassium metal and water are mixed, a chemical reaction occurs. This exothermic reaction produces hydrogen gas and potassium hydroxide, which dissolves in the remaining water. This reaction can be vigorous and produce light, heat and sound.
What will litmus paper do to a solution with Na Cl?
Litmus paper doesn't "do anything" to a solution. Litmus paper has some dyes on it, so some of the dyes might leak into the solution though. NaCl won't do anything to Litmus paper either. Salt, when dissolved in water, maintains a neutral solution. Litmus paper only changes color when there is a pH change. So, nothing really will happen.
What element oxide turned red litmus paper to blue?
A basic element oxide, such as sodium oxide (Na2O) or potassium oxide (K2O), can turn red litmus paper blue. These oxides react with water to form alkaline solutions, raising the pH and causing the color change in litmus paper. The shift from red to blue indicates the presence of a basic substance.
How can we prepare litmus solution in lab?
To prepare a litmus solution in the lab, you can dissolve powdered litmus in distilled water to create a purple solution. Stir the mixture well to ensure the litmus is fully dissolved. Adjust the concentration of the solution by adding more litmus or water as needed.
