When you add ammonium (NH4^+) with sodium hydroxide (NaOH), it forms ammonia (NH3) gas, water (H2O), and sodium chloride (NaCl) salt through a reaction called neutralization. This reaction can release heat, and can be used to identify the presence of ammonium ions in a solution.
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.
When sodium hydroxide is added to copper bromide, a precipitation reaction occurs, leading to the formation of solid copper hydroxide and sodium bromide in solution. The copper hydroxide is insoluble in water and will appear as a precipitate.
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.
When you put zinc dust in sodium hydroxide solution, sodium zincate and hydrogen are formed. Zn + 2 H2O + 2 NaOH → Na2Zn(OH)4 + H2
When you add ammonium (NH4^+) with sodium hydroxide (NaOH), it forms ammonia (NH3) gas, water (H2O), and sodium chloride (NaCl) salt through a reaction called neutralization. This reaction can release heat, and can be used to identify the presence of ammonium ions in a solution.
Adding more sodium hydroxide will increase the concentration of the reactant in the reaction, leading to more successful collisions between particles and thus speeding up the reaction. This happens because there are more particles available to react with hydrogen chloride, resulting in a higher reaction rate.
When sodium hydroxide is added to copper bromide, a precipitation reaction occurs, leading to the formation of solid copper hydroxide and sodium bromide in solution. The copper hydroxide is insoluble in water and will appear as a precipitate.

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.
It is not recommended to put sodium hydroxide (caustic soda) directly into a lead-acid battery as it can damage the battery's plates and compromise its performance. Only distilled water or sulfuric acid should be used to maintain the electrolyte level in a lead-acid battery.
