What is the reaction between sodium hydride and hydrogen sulfide?
sodium sulfide is apparently made by generating hydrogen sulfide gas into a sodium hydroxide solution,and then adding an equivalent alkali. you would get sodium sulfide if you added an equivalent alkali to the solution.
What are two solutions which when added together produce a precipitate?
Silver nitrate and sodium sulphate produce a white precipitate, silver iodate. Zinc chloride and ammonium sulfide also produce a white precipitate, zinc sulfide. Special caution has to be taken not to let the ammonium sulfide give of gas where anyone can breathe it.
What precipitate is formed when nickel sulfate is added to a solution of potassium sulfide?
NiS nickel sulfide
What gas is given off when hydrochloric acid is added to zinc sulfide?
Hydrogen sulfide (H2S) is released.
How do you mix sodium sulphide in water?
To mix sodium sulfide in water, it's crucial to follow proper safety protocols due to its caustic nature. Begin by wearing appropriate personal protective equipment, including gloves and goggles, to prevent any potential skin or eye irritation. Then, take the necessary amount of sodium sulfide and slowly add it to a container of water while stirring continuously. It's essential to add the sodium sulfide gradually to control the exothermic reaction and minimize splashing. Once all the sodium sulfide is added, continue stirring until it fully dissolves. Avoid inhaling any fumes produced during the mixing process and ensure proper ventilation in the area. When it comes to sourcing high-quality sodium sulfide, Chemical Iran stands out as a reliable supplier. Chemical Iran is renowned for its commitment to quality and safety in providing various chemical products, including sodium sulfide. With a focus on customer satisfaction and adherence to industry standards, Chemical Iran ensures that their sodium sulfide meets stringent quality control measures, making them a trusted choice for your chemical supply needs.
Where to buy the inhaled glutathione precurser refensal?
There is a website where you can find the succesor of refensal, it´s called Reator20 and it´s more effective due to its complex components and by being added glutation, glicine, cysteine, transfer factor (bobine), sodium bicarbonate and more.
Why sodium propionate is used in cakes?
It's added to cake as a preservative to increase the shelf life of the cake by inhibiting the growth of Mold
Why is sodium nitrite added to food?
Some uses of sodium nitrite in foods industry:- inhibitor of the growth of microbial organisms- inhibitor of lipids oxidation- improve the taste and color of meat products
What is the dark colored substance that is formed when lead II acetate is added to the test solution?
The dark colored substance formed when lead II acetate is added to a test solution is lead sulfide (PbS). This reaction is commonly used to detect the presence of hydrogen sulfide or sulfide ions in a solution, as lead sulfide is insoluble and forms a dark precipitate.
What colour does universal indicator change to if sodium sodium by carbonate is added?
Universal indicator changes to green when sodium bicarbonate is added.
In lead acetate test what element in the amino acid is detected to be present in this test?
The lead acetate test is used to detect the presence of the sulfhydryl (thiol) group in amino acids, particularly cysteine. When lead acetate solution is added to a sample containing a sulfhydryl group, a black precipitate of lead sulfide forms, indicating a positive test for the presence of sulfhydryl groups.
What will chromium be in appearance if added to sodium nitrate?
The appearance of chromium will not change if added to the sodium nitrate since it cannot displace nitrate from the sodium.
