The lack of change in color of a conical flask containing leaves and potassium hydroxide is likely due to the chlorophyll in the leaves not being exposed to light. Without light, the chlorophyll cannot undergo the process of photosynthesis or react with the potassium hydroxide to produce color changes.
What else can I help you with?
What happens when potassium hydroxide reacts with litmus paper?
Potassium hydroxide is a strong base that will turn red litmus paper blue, indicating its basic nature. The hydroxide ions in potassium hydroxide react with the indicator dye in the litmus paper, causing a color change.
Why can't potassium hydroxide be used to test for carbon dioxide?
it is because potassium hydroxide will react with carbon dioxide to form potassium carbonate and water. but potassium carbonate is soluble, so there will be no visible change to see if there is carbon dioxide emitted
What colour would universal indicator change with potassium hydroxide?
It would make it a blue color, meaning alkaline.
When naming the compound containing potassium and chlorine change the suffi of anions name to?
When naming the compound containing potassium and chlorine, the suffix of the anion's name changes from "-ine" to "-ide". Thus, the compound formed is called potassium chloride.
Hydrochloric acid reacts with potassium hydroxide to produce a salt water and heat chemical or physical?
The reaction between hydrochloric acid and potassium hydroxide is a chemical reaction that forms water and potassium chloride salt. It is an exothermic reaction, meaning that heat is released as a result of the reaction.
When naming a compound containing potassium and chlorine change the suffix of the anion name to?
When naming a compound containing potassium and chlorine, you change the suffix of the anion name to "-ide." In the case of potassium and chlorine forming KCl, the compound is named potassium chloride.
What happens when potassium hydroxide reacts with litmus paper?
Potassium hydroxide is a strong base that will turn red litmus paper blue, indicating its basic nature. The hydroxide ions in potassium hydroxide react with the indicator dye in the litmus paper, causing a color change.
When hydrochloric acid is mixed with potassium hydroxide is it a chemical change?
Yes - you have an acid and base and the resultant products are a salt (Potassium Chloride) and water
Why can't potassium hydroxide be used to test for carbon dioxide?
it is because potassium hydroxide will react with carbon dioxide to form potassium carbonate and water. but potassium carbonate is soluble, so there will be no visible change to see if there is carbon dioxide emitted
What colour would universal indicator change with potassium hydroxide?
It would make it a blue color, meaning alkaline.
When naming the compound containing potassium and chlorine change the suffix of the anion's name to .?

When naming the compound containing potassium and chlorine change the suffi of anions name to?
When naming the compound containing potassium and chlorine, the suffix of the anion's name changes from "-ine" to "-ide". Thus, the compound formed is called potassium chloride.
Hydrochloric acid reacts with potassium hydroxide to produce a salt water and heat chemical or physical?
The reaction between hydrochloric acid and potassium hydroxide is a chemical reaction that forms water and potassium chloride salt. It is an exothermic reaction, meaning that heat is released as a result of the reaction.
Is the exploding of potassium metal in water a chemical change?
Yes, the exploding of potassium metal in water is a chemical change. This reaction involves the formation of new substances (potassium hydroxide and hydrogen gas) with different chemical properties than the original substances (potassium metal and water).
Does potassium change a different colour when mixed with water?
Potassium metal does not change color when mixed with water. However, it reacts vigorously with water, producing hydrogen gas and forming potassium hydroxide. The reaction is exothermic, releasing a significant amount of heat. This reaction is often used to demonstrate the reactivity of alkali metals with water.
Ask us naming the compound containing potassium and chlorine change the suffix of the anion's name to .?
The compound containing potassium and chlorine would be called potassium chloride. When naming ionic compounds, the suffix of the anion's name is usually changed to -ide.
Is hydrochloric acid reacts with potassium hydroxide to produce a saltwater and heat a physical or chemical change?
The reaction of hydrochloric acid with potassium hydroxide is a chemical change because new substances (salt and water) are formed that have different chemical properties than the original reactants. The release of heat is an indicator of a chemical reaction taking place.
