Is sodium hydroxide used for making common salt?
No
What is the name of the salt when hydroxide reacts with sulphuric acid?
It depends on the metal cation in the hydroxide. General equation for group (I) metals) is 2MOH + H2SO4 = M2SO4 + 2H2O And for Group(II) metals M(OH)2 + H2SO4 = MSO4 + 2H2O
Why is calcium hydroxide used in food?
It's used "for processing water (for alcoholic and soft drinks)" -http://en.wikipedia.org/wiki/Calcium_hydroxide
Why would solid calcium hydroxide be used to test for carbon dioxide?
I'm not too sure but: It would turn the limewater 'milky' or chalky: CO2 is bubbled though and solid precipitate of calcium carbonate is formed
Why is calcium hydroxide used to neutralize acids?
Because it is an alkali. ( soluble base). Remember for all acid reactions. ; - Acid + Alkali = salt + water Acid + Base = Salt + Water. So if you have any acid , say hydrochloric acid , then the salt formed is calcium chloride and water. Here is the reaction equ'n. 2HCl + Ca(OH)2 = CaCl2 + 2H2O
How do you apply calcium hydroxide?
calcium hydroxide is used to neuralise the acidity in soil
Is there any difference in lime water and slaked lime . If any why do you use different name?
Yes, there is a difference. Slaked lime is the term used to refer to solid calcium hydroxide, and lime water is a calcium hydroxide solution. Admittedly, two distinct terms seems like overkill, but it happens a lot... for example, "salt" and "brine" is essentially the same situation. The terms are historical, and most chemists would just say "calcium hydroxide" and "calcium hydroxide solution" instead.
Why isn't magnesium hydroxide used as an antacid opposed to calcium hydroxide?
Magnesium, although having the same valence electron configuration as calcium, is toxic to humans at lower levels. Humans can handle having more ionic calcium in their system than they can ionic magnesium, so calcium salts are more commonly used as antacids. However, I don't believe calcium hydroxide is what is used as an antacid in humans - hydroxides are strong bases and I would think this would be very caustic and could cause chemical burns to the digestive tract. I believe the actual antacide is calcium carbonate. However, the above paragraph about why magnesium versus calcium is still true for a carbonate salt.
Explain why calcium hydroxide can be used in this way?
Calcium hydroxide is used to test for carbon dioxide because the product of the reaction, calcium carbonate, is insoluble, and easily visible.
What is the salt type of calcium oxide?
It is an OXIDE-salt, although it normally is not called a 'salt' but an 'oxide'. But strictly speaking it IS a salt like eg. CaS (calcium sulfide) CaO, calcium oxide, dry chalk, used as dry desinfectant eg. in mass graves slightly soluble in water, forming calcium hydroxide Ca(OH)2
Is CaCO3 a salt?
"Salt" is the common name for sodium chloride, used in cookery etc. In chemistry a salt is produced by the reaction of an acid with an hydroxide- in the case of sodium chloride the acid is hydrochloric acid and the hydroxide is sodium hydroxide. Calcite, calcium carbonate, CaCO3, is als a salt- and is precipitated when calcium hydroxide is reacted with carbonic acid, H2CO3
Which 4 acids are important for industry?
Aluminum hydroxide and Ammonia, Calcium hydroxide and sodium hydroxide. Aluminum hydroxide is used in color fast fabrics and water purification. ammonia is used in cleaners and fertilizer, Calcium hydroxide is used in leather making and mortar and plaster making. sodium hydroxide is used to make soap.
What is calcium hydroxide used for?
Calcium hydroxide many varied uses. It is used to make mortar or plaster, it is used by dentists during a root canal, and it can be used as a hair straightener just to name a few.
What kind Of Carbide is needed for lamp?
Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide. Acetylene is extremely flammable, giving a colorless flame. The calcium hydroxide present gives the flame its visibility. Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide.
