If you add copper sulfate to sodium hydroxide, a double displacement reaction will occur. The copper sulfate will react with the sodium hydroxide to form copper hydroxide, which is a blue solid, and sodium sulfate, which is a soluble compound. This reaction is often used in qualitative analysis to test for the presence of copper ions.
Adding iodine to sodium hydroxide will result in brown color due to the formation of sodium iodide and sodium hypoiodite.
It is not recommended to add sodium bicarbonate (baking soda) to sodium hydroxide as it can cause a reaction that releases carbon dioxide gas. This reaction can be exothermic and may cause splattering of the solution. It is safer to add these chemicals separately to your desired solution.
To make a 5% water solution of sodium hydroxide, you would mix 5 grams of sodium hydroxide with 95 grams of water. This will give you a total of 100 grams of solution, with 5% of it being sodium hydroxide. Remember to always add the sodium hydroxide to the water slowly and with caution due to its caustic nature.
When you add universal indicator to sodium hydroxide, it will typically turn purple or dark blue in color, indicating that the solution is strongly alkaline.

When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
To effectively dilute sodium hydroxide for safe handling and use, slowly add the sodium hydroxide to water while stirring constantly. Do not add water to sodium hydroxide as it can cause a violent reaction. Wear appropriate protective gear, such as gloves and goggles, and work in a well-ventilated area to prevent exposure to fumes.
No, adding water to sodium hydroxide will not lower the pH. Sodium hydroxide is a strong base, and when dissolved in water, it dissociates to produce hydroxide ions, which make the solution more basic. To lower the pH of a sodium hydroxide solution, you would need to add an acid to neutralize the base.
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
Sodium react with water forming a base - sodium hydroxide - and releasing hydrogen. Add an acid for neutralization.
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
