What happens when excess of CO2 is passed through lime vessel?
When excess CO2 is passed through a lime vessel, it reacts with the lime (CaO) to form calcium carbonate (CaCO3) through a process called carbonation. This reaction removes the excess CO2 from the system and produces calcium carbonate as a white precipitate.
Why is calcium carbonate used to neutralize acidic water instead of calcium oxide?
Because if you over correct, excess calcium carbonate is all but harmless, whilst excess sodium hydroxide can be corrosive and toxic.
Why is excess magnesium is used for reacting it with sulphuric acid and powder?
Excess magnesium is used in reactions with sulfuric acid to ensure complete conversion of the acid into magnesium sulfate and hydrogen gas. The excess magnesium helps to drive the reaction to completion, allowing for efficient hydrogen gas production and preventing the formation of unreacted sulfuric acid. Additionally, using excess magnesium helps to control the reaction rate and mitigate the risk of localized overheating or reaction hazards.
How can you get crystals from the reaction of magnesium and sulphuric acid?
To obtain crystals from the reaction of magnesium and sulfuric acid, you can follow these steps: 1) Mix magnesium ribbon with diluted sulfuric acid in a beaker. 2) Allow the reaction to occur, which will produce hydrogen gas and magnesium sulfate. 3) Filter the mixture to remove any excess magnesium or impurities. 4) Evaporate the filtered solution to allow the magnesium sulfate to crystallize and form crystals.
What is observed when carbon dioxide gas is passed through limewater for a long duration?
When carbon dioxide gas is passed through limewater (a solution of calcium hydroxide) for an extended period, the solution initially turns milky due to the formation of calcium carbonate, which is a result of the reaction between carbon dioxide and calcium hydroxide. Over time, if excess carbon dioxide is introduced, the calcium carbonate can dissolve back into the solution, forming calcium bicarbonate. This process can lead to the limewater becoming clear again after the initial turbidity.
One mole of calcium phosphide on reaction with excess of water gives what?
One mole of calcium phosphide on reaction with excess water produces calcium hydroxide and phosphine gas. This reaction can be represented as Ca3P2 + 6H2O → 3Ca(OH)2 + 2PH3.
How excess acidity can be treated using calcium hydroxide?
Calcium hydroxide, Ca(OH)2 is a base and neutralizes acid. When a solution is acidic it contains excess hydrogen (H+) ions, calcium produces the hydroxide ion (OH-) in water, which reacts wit h the H+ ions to produce water. OH- + H+ --> H2O
Why only magnisium sulphate and calcium sulphate cause hardness of water not sodium sulphate?
Magnesium sulfate and calcium sulfate cause hardness in water because they are slightly soluble in water, leading to the presence of excess ions in the water. Sodium sulfate, on the other hand, is highly soluble and does not produce excess ions that contribute to water hardness.
Is sodium sulfate more soluble at high pH or low pH?
Sodium sulfate is more soluble at high pH because it is a salt of a strong base (sodium hydroxide) and a weak acid (sulfuric acid). At high pH, the excess hydroxide ions can react with the sulfate ions to form more soluble compounds, increasing the solubility of sodium sulfate.
When excess of ammonia is added to aqueous zinc sulfate does the precipitate dissolve?
Yes. The ammonia will form ammonium hydroxide. The ammonium cation (NH4+) will react with SO4^2- to form the soluble salt ammonium sulfate, (NH4)2SO4. According to Le Chatelier's Principle, this will push the reaction to the right, thus forming more ammonium sulfate from the insoluble zinc sulfate.
Aluminum sulfate reacts with ammonium hydroxide to form what?
it forms a white precipitate ; Al(OH)3 and ammonium sulfate with additional excess NH4OH,still white ppt wont dissolve this means Aluminum dont make a complex with ammonia
Why was the copper II oxide added in excess to dilute sulfuric acid to form the soluble salt copper II sulphate?
Copper II oxide was added in excess to ensure that all the sulfuric acid reacted, forming water and copper II sulfate. This method helps to avoid any excess sulfuric acid remaining in the solution, ensuring that all copper II oxide reacts completely to form the desired copper II sulfate salt.
How to tranform cupric sulfate to cupric hydroxide?
Put drops of Sodium, Potassium, or Ammonium Hydroxide in it. The Cupric hydroxide will precipitate out in blue colour. Dont put excess hydroxide or there will be a formation of another intense blue complex compound
When 400.0 g of ammonia reacted with excess sulfuric acid to produce ammonium sulfate 1463.0 g of product were obtained What is the percent yield of ammonium sulfate for this reaction?
94.25 - 94.28
300 g of ammonia react with 36 moles of sulfuric acid to produce ammonia sulfate how many moles of excess sulfuric acid are left over after the reaction is complete?
26.9 - 27.4
When 300.0 g of ammonia reacted with excess sulfuric acid to produce ammonium sulfate 985.0 g of product were obtained What is the percent yield of ammonium sulfate for this reaction?
84.62 - 84.66 or 84.64%.
What is milk of lime?
the milk of lime is... wait for this... the lime of milk. ================================================================== Kidding aside from the first answer, milk of lime is another common name for limewater, a saturated solution of calcium hydroxide. It got its name from the process of its preparation, wherein excess calcium hydroxide is stirred in pure water and filtering off the excess insoluble Ca(OH)2. When excess calcium hydroxide is added to limewater, a suspension of calcium hydroxide particles remains, giving it a milky aspect, in which case it has the common name of milk of lime.
