what would be the effect of placing the standard sodium hydroxide in a baker which contained some residual water in the beaker?
The standard solution would be diluted. However, depending upon what you do with it next the dilution may or may not affect the accuracy of the results.
If I had one gollan of sodium hydroxide solution which had a concecentration of two pounds of sodium hydroxide per gallon, What would be the concentration of four gallons of that acid?
When sodium hydroxide (NaOH), also known as caustic soda or lye, comes into contact with water, it undergoes a highly exothermic reaction, meaning it releases heat. This reaction is known as neutralization. The water molecules react with the sodium hydroxide, causing the release of heat energy.
If you were to place standard sodium hydroxide into a beaker that contains residual water, you would observe several effects:
1. Heat Release: When sodium hydroxide comes in contact with water, it will release a significant amount of heat. This release of heat can cause the temperature of the mixture to rise rapidly, potentially leading to boiling or splattering of the solution.
2. Increased Solution Volume: The reaction between sodium hydroxide and water produces a new solution, sodium hydroxide solution (NaOH(aq)). The volume of this solution will be greater than the initial volume of water due to the addition of sodium hydroxide.
3. Dissolution: Sodium hydroxide is highly soluble in water. As it reacts with water, it will dissolve, forming a homogeneous solution. The resulting solution will be alkaline, as sodium hydroxide is a strong base.
It is important to note that the reaction between sodium hydroxide and water is highly exothermic and can be dangerous if not handled properly. Always exercise caution when working with sodium hydroxide and ensure proper safety measures, such as wearing protective gloves and eyewear.
