What else can I help you with?
Does caustic kill bacteria?
Yes, caustic substances like sodium hydroxide can kill bacteria by disrupting their cell membranes and denaturing their proteins. However, care should be taken when using caustic chemicals as they can be harmful to humans and the environment.
What is lye made of?
Lye (also known as caustic soda) is a corrosive alkaline substance, commonly, sodium hydroxide (NaOH). Previously, lye was among the many different alkalis leached from hardwood ashes.[1] Now, lye is commercially manufactured using a membrane cell method, which is an improvement from the previous diaphragm cell methods of Castner-Kellner, Gibbs, and Nelson. answer taken from: http://en.wikipedia.org/wiki/Lye
Can caustic soda be used as weed killer?
Yes, caustic soda (sodium hydroxide) can be used as a weed killer. When sprayed on weeds, it disrupts the plant's cell structure, causing it to die. However, it is a strong chemical and should be used with caution as it can harm other plants and the environment.
What is a still cell?
A still cell refers to a type of electrolytic cell used for producing chlorine gas and caustic soda (sodium hydroxide) through the electrolysis of brine (sodium chloride solution). It is characterized by its stationary or non-moving electrodes and typically operates at lower temperatures compared to other types of electrolytic cells.
Where would the black spots appear on an emulsion prepared 3 hours after the pulse?
Exterior of the cell
Which is better process to prepare NaOH nelson cell or castner-kellner?
Caster kellner's cell method is better because, 1- it gives about 100% pure NaOH. 2-a large quantity of NaOH can be prepared in a short time. 3- NaOH and Cl2 are formed in separate chamber and can not react with each other.
Why secondary cell is known as denuder in castner kellner?
cause they smell like pickles
Why secondary cell is known as Denuder in Castner Kellner process?
A denuder is used in the Castner-Kellner process to remove any unreacted chlorine gas before it reaches the secondary cell. This is important to prevent contamination of the sodium hydroxide solution in the secondary cell and to ensure the purity of the final product. The denuder helps to improve the overall efficiency and effectiveness of the electrolysis process in producing sodium hydroxide.
How is chlorine prepared pure form?
Chlorine is a gas so mostly we get in pure form as, 1- By action of sulphuric acid on any chloride salt, 2- From castner-kellner's cell during the formation of caustic soda (Now Gibbs cell is also used) and 3- by old Decon's process.
What is advantages and disadvantages of castner kellner process?
The Castner-Kellner process is a method for producing sodium metal through the electrolysis of molten sodium hydroxide. One advantage of this process is its ability to produce high-purity sodium metal. However, a disadvantage is that it requires a significant amount of energy to operate due to the high temperatures needed for the electrolysis process. Additionally, the process can be complex and expensive to set up and maintain.
What is the gas liberated at anode in the manufacture of caustic soda using nelson cell?
The raw material for the manufacturing of caustic soda is sodium chloride so gas liberated at anode is chlorine.
Does caustic kill bacteria?
Yes, caustic substances like sodium hydroxide can kill bacteria by disrupting their cell membranes and denaturing their proteins. However, care should be taken when using caustic chemicals as they can be harmful to humans and the environment.
How is sodium metal prepared?
Using Downs process, by the electrolysis of molten sodium chloride. This is done in a Downs Cell in which the NaCl is mixed with calcium chloride to lower the melting point below 700 °C. As calcium is less electropositive than sodium, no calcium will be deposited at the cathode. This method is less expensive than the previous Castner process of electrolyzing sodium hydroxide.
