What is observed when potassium iodide is added to the solution of lead nitrate?
A yellow precipitate of lead iodide forms, while potassium nitrate remains in solution. This reaction is a double displacement reaction with an exchange of ions between the two compounds.
What forms a blue solution?
A blue solution can be formed by substances that absorb light in the red/yellow part of the spectrum, allowing blue light to be transmitted or reflected. Copper sulfate, methylene blue, and cobalt chloride are examples of compounds that can form blue solutions.
What is the color of phenolic solution?
Phenolic solution can vary in color depending on the specific compound it contains. It can range from colorless to yellow, red, or brown. The color is often due to the presence of phenolic compounds such as phenol or resorcinol.
What are compounds that forms hydroxide ions in solution?
Compounds that form hydroxide ions in solution include metal hydroxides like sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). These compounds dissociate in water to release hydroxide ions (OH-) and cations.
How does potassium and sodium thiosulphate turn yellow?
Potassium and sodium thiosulfate can turn yellow due to the formation of a colored complex with iodine. When iodine is added to a solution containing thiosulfate, it forms a triiodide ion which has a yellow color. This reaction is commonly used in chemistry as an indicator for the presence of thiosulfate ions in solution.

What is the colour of barium chloride solution?
A solution of barium chloride is added to a solution of potassium chromate, a yellow precipitate forms.
What is the color of phenolic solution?
Phenolic solution can vary in color depending on the specific compound it contains. It can range from colorless to yellow, red, or brown. The color is often due to the presence of phenolic compounds such as phenol or resorcinol.
Compare and contrast acid and bases?
Acid and Bases are different by its concentration of Hydrogen and Hydroxide. Acid is any compound that forms H+ ions in solution and base is a compound that forms OH- ions in solution. But Both are compounds forming a type of ion in a solution.
What does red indicate?
Phenol red indicates for acidic pH. When the red solution turns yellow it means the solution has a low pH. For Example: CO2 dissolves into water and forms carbonic acid which lowers the pH and the solution would turn yellow.
What is a new substance that forms as the result of a chemical reaction is a gas?
An example of a new substance that forms as a gas during a chemical reaction is carbon dioxide (CO2). This gas is often produced when carbon-containing compounds, such as glucose, burn in the presence of oxygen.
What are compounds that forms hydroxide ions in solution?
Compounds that form hydroxide ions in solution include metal hydroxides like sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). These compounds dissociate in water to release hydroxide ions (OH-) and cations.
What happen when ferric thiocyanate is react with fluoride ion?
yellow solution forms some sort of ferric flouro thiocyanto complex

Is magnesium bromide soluble?
Yes, magnesium bromide (MgBr2) is soluble in water. It forms a colorless to pale-yellow solution when dissolved in water.
