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.
Because if you over correct, excess calcium carbonate is all but harmless, whilst excess sodium hydroxide can be corrosive and toxic.
Excess calcium is stored in the bones when blood calcium levels increase. This process is regulated by hormones such as calcitonin and parathyroid hormone, which help maintain calcium balance in the body.
When carbon dioxide is passed through lime water in excess, a white precipitate of calcium carbonate is formed. This is because carbon dioxide reacts with the calcium hydroxide in lime water to form calcium carbonate, which is insoluble and appears as a solid in the solution. This reaction is used as a test for the presence of carbon dioxide gas.

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.
The reaction of zinc nitrate and excess sodium hydroxide begins with precipitation of zinc hydroxide ( Zn(OH)2 ), followed by dissolvement after adding excess sodium hydroxide ( 2 OH- ) to formation of zinc aat-ions ( [Zn(OH)4]2- )
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
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.
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. Milk of lime is an alkaline solution with a pH of 12.3.
Zinc hydroxide dissolves in excess dilute sodium hydroxide because it forms a complex ion, [Zn(OH)4]^2-, which is soluble in aqueous solution. This complex ion helps stabilize the zinc hydroxide and prevents it from precipitating out of solution.
Most medications include antacids, which are weak bases (e.g. calcium carbonate, aluminum hydroxide, magnesium hydroxide) to neutralize excess stomach acid.
Gradually dissolve potassium hydroxide crystals in pure water. In a certain point, a precipitation starts as further dissolving does not take place and you've made a solution of saturated potassium hydroxide.
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.
The white precipitate of zinc hydroxide dissolves in excess ammonium hydroxide because of the formation of the complex ion [Zn(NH3)4]2+. This complex ion is soluble in water, leading to the dissolution of the precipitate. The excess ammonium hydroxide provides additional ammonia molecules to form more of the soluble complex ions, increasing the solubility of zinc hydroxide.
Because if you over correct, excess calcium carbonate is all but harmless, whilst excess sodium hydroxide can be corrosive and toxic.
Common bases found in antacids include magnesium hydroxide, calcium carbonate, and aluminum hydroxide. These bases work by neutralizing excess stomach acid to provide relief from conditions like heartburn and indigestion.
