What else can I help you with?
Is hydroxide oil?
No, hydroxide is a highly basic anion (negatively charged ion). Properties vary depending on the cation (positive ion) it is paired with. Most hydroxides are solids that are insoluble in water. Those that are water soluble can cause severe chemical burns.
Why must sodium be stored under paraffin?
Sodium is a highly reactive metal that reacts vigorously with air and moisture to form sodium hydroxide and hydrogen gas. Storing sodium under paraffin oil helps prevent its exposure to moisture and oxygen, which can prevent its reactivity and potential hazards.
Reaction between methyl salicylate and sodium hydroxide?
When methyl salicylate (oil of wintergreen) reacts with sodium hydroxide (NaOH), it undergoes saponification to form sodium salicylate and methanol. This reaction is a base-catalyzed ester hydrolysis reaction that converts the ester functional group of methyl salicylate into a carboxylate salt.
Why is sodium hydroxide used in oven cleaners?
Sodium hydroxide can dissolve grease, oils, fats and protein based deposits. It helps convert these substances into a form of soap (the saponification process) which can then be easily washed away.
Why must sodium be stored in an inert substance?
Sodium reacts vigorously with air and moisture, forming sodium hydroxide and hydrogen gas. Storing sodium in an inert substance, such as kerosene or mineral oil, helps prevent these reactions and keeps the sodium from catching fire or exploding.
What happens when sodium hydroxide is mixed with vegetable oil?
soap+glycerine
Is sodium hydroxide soluble in oil?
No, sodium hydroxide is not soluble in oil due to its hydrophilic nature. Sodium hydroxide is a strong base that is soluble in water but will not dissolve in nonpolar solvents like oil.
What is the balanced equation for the reaction of castor oil and sodium hydroxide?
The balanced equation for the reaction of castor oil (triglyceride) and sodium hydroxide (NaOH) is: Triglyceride + 3NaOH → Glycerol + 3Soap This reaction is known as saponification, which produces glycerol and soap molecules from the reaction between the ester bonds in the triglyceride and the hydroxide ions in sodium hydroxide.
What will happen if you put a sodium hydroxide in cooking oil?
It becomes soap.
What ingredients are in a melt and pour soap base?
Typically there are a number of recipes for melt and pour soaps and they would have a variance in ingredients, with some ingredients being used in different recipes.Recipe 1Filtered Water (Aqua), Glycerine BP, Palm Kernel Oil, SLES 70%, SLES 25%, Caustic Soda, VestasolRecipe 2Glycerin, Propylene Glycol, Sodium Stearate, Sodium Laureth Sulfate, Sorbital, Coconut Oil, Sodium Myristate, Triethanolamine, Sodium Laurate, Sodium Cocoate, Purified Water, Parfum, Natural Extract, Coloring Agent
What color would Vegetable oil when in contact with Copper Sulfate and Sodium hydroxide?
When vegetable oil comes into contact with copper sulfate and sodium hydroxide, it generally remains a yellowish or light brown color. The reaction primarily involves the sodium hydroxide acting as a base and potentially saponifying the oil, but the vegetable oil itself does not change color significantly in this process. The copper sulfate may impart a blue hue to any aqueous layer, but the oil layer will retain its original color.
Why do sodium kept immersed in kerosene oil do not burn?
Sodium reacts violently with water, releasing hydrogen gas and forming sodium hydroxide. When sodium is kept immersed in kerosene oil, it is isolated from water, preventing the reaction from occurring. Kerosene oil acts as a barrier to keep oxygen away from the sodium, further preventing combustion.
What happens if you accidentally pour antifreeze where your engine oil goes?
you have a big problem

Why must sodium be stored under paraffin?
Sodium is a highly reactive metal that reacts vigorously with air and moisture to form sodium hydroxide and hydrogen gas. Storing sodium under paraffin oil helps prevent its exposure to moisture and oxygen, which can prevent its reactivity and potential hazards.
What is the saponification value of castor oil?
Saponification value is the amount of pure sodium hydroxide needed to saponified 100 grams of oil No. saponified castor oil is from 12.5 to 13 grams
What happens when you mix an alkali with oil?
When an alkali, such as sodium hydroxide, is mixed with oil, a process called saponification occurs. This reaction produces soap and glycerol. The alkali reacts with the oil's fatty acids to form soap molecules, which can then emulsify and help dissolve grease and dirt.
