Which is more basic calcium carbonate or calcium oxide?
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base. Calcium oxide is commonly called lime or quicklime.Calcium carbonate is a compound of calcium, carbon, and oxygen with the formula CaCO3. It is mildly basic and will not react with water nor is it water soluble. It is commonly called calcite, limestone, or marble.
How are the salts named?
Salts made of a metal and a nonmetal are named this way: [metal] [nonmetal root]-ide Examples: sodium + chlorine = sodium chloride potassium + iodine = potassium iodide Salts made from a metal or other complex cation and a nonmetal or other complex anion are named based on the cation and anion names: ------------------------------- ammonium ion + hydroxide ion = ammonium hydroxide sodium ion + hypochlorite ion = sodium hypochlorite calcium ion + chloride ion = calcium chloride
Name the alkali metals?
List of Alkali: Lithium hydroxide Sodium hydroxide Potassium hydroxide Rubidium hydroxide Caesium hydroxide Francium hydroxide Strontium hydroxide Barium hydroxide Ammonium hydroxide Calcium hydroxide Magnesium hydroxide
How does calcium enter your body?
You ingest calcium in the food you eat and the milk you drink.
Will calcium hydroxide eat flesh?
Considering some of its uses, you can guess that calcium hydroxide is not going to "eat flesh" the way that Sodium Hydroxide is known to. Calcium hydroxide is the depilatory agent in Nair. It is used as a lye substitute in no-lye hair relaxers. It is sometimes used as a calcium supplement fortified baby formula. It is used in home food preservation in the making of pickles. With that said, it still is not too friendly to your skin. Contact with pure Ca(OH)2 or very concentrated solutions of it can cause chemical burns or blistering - the longer the exposure, the worse the effect. Chronic exposure will cause persistent skin irritation and nasty rashes. Breathing in the dust can cause lung problems and chemical bronchitis as it irritates all the membranes. If you get it in your eyes it will cause severe irritation, and can cause ulceration and even blindness. Swallowing it can cause severe pain, vomiting, and diarrhea. The tissues inside your digestive system are not as tough as your skin. The damage from swallowing it can cause death. The damage to the esophagus can cause ulceration and/or narrowing (which makes swallowing difficult). The ulceration can be bad enough to cause significant internal bleeding. Compared to Sodium Hydroxide, it is much less damaging. Getting Ca(OH)2 on your skin will not normally cause much immediate damage and most of the bad effects can be averted by washing it off soon after exposure. NaOH, by contrast immediately starts causing significant damage when you come into direct contact with it. The extreme alkalinity of NaOH coupled with its strong hygroscopic nature means it will quickly dissolve into any skin or membrane moisture and begin reacting with the surrounding tissue. NaOH has a solubility in water of 1110 g/L (20 °C) while Ca(OH)2 only has a solubility of 0.173 g/100 mL (20 °C). Since Ca(OH)2 is only a weak base and not nearly as soluble as NaOH (which is a strong base) it doesn't have the "flesh eating" properties of Sodium Hydroxide.
Does calcium hydroxide cause rust?
No, calcium hydroxide does not cause rust. Rust is a specific type of corrosion that occurs on iron and its alloys, while calcium hydroxide is a chemical compound that does not react with iron in a way that causes rusting.
Why can calcium hydroxide be used to test for carbon dioxide?
I have just answered this question as part of homework myself, limewater is a common name for Ca(OH)2 (calcium hydroxide) and when limewater and carbon dioxide meet they instantly react in a visible way. The limewater turns cloudy, sort of like when milk and water meet. Hope this helps
Is calcium acetate an acid or base?
Ca(CH3COO)2Neutral as the is the calcium salt of acetic acid.
Is calcium nitrate plus ammonium hydroxide a physical change?
No, the reaction between calcium nitrate and ammonium hydroxide is a chemical change, as new compounds are formed with different properties than the original substances. This will typically result in the formation of solid calcium hydroxide and ammonium nitrate, which are not reversible through physical means.
What gas is produced when calcium metal is dropped in water?
HYdrogen. The Group (II) Alkaline Earth elements, of which calcium is one, react in a similar way the Group (I) Alkali metals, but less vigorously. So like sodium and water produces sodium hydroxide and hydrogen . # Then calcium and water produce calcium hydroxide and hydrogen. Here is the reaction eq'n. Ca(s) + 2H2O(l) = Ca(OH)2(aq) + H2(g) .
Sulphuric Acid plus Calcium Hydroxide equals?
Calcium Sulphate and water. The easy way to see this is that you have an acid reacting with an alkali (hydroxides are always alkalis), so the reaction is a neutralisation reaction, meaning that it produces water. This leaves a sulphate ion and a calcium ion, which react to form the salt calcium sulphate.
Is calcium hydroxide like carbon dioxide?
Well ... they're both chemical compounds ... Other than that, no; they're different in just about every possible way.
Is calcium hydroxide safe to consume?
It is unsafe to drink because and any hydroxide is created by hydrochloric acid, Calcium Hydroxide is therefore unsafe to drink. However the dilute solution of Calcium Hydroxide is Limewater, which is not recommended to drink because it is the main way to test for Carbon Dioxide. It can make you feel sick and cause painful vomiting, but other than that has no other affect on the human body.

Why is a chemical reaction created between calcium and water?
Calcium is not found as the metal in nature. It prefers to be a compound. Nature abhors energy and always tries to minimize it. That is why iron and steel rust. Nature prefers iron to be lower energy- rust. In the same way, calcium is far lower energy and far more stable as calcium hydroxide than calcium metal. So calcium reacts with water because it is so energetically favorable. Ca + 2H2O -------> Ca(OH)2 + H2
Why is magnesium hydroxide used as an antacid instead of sodium hydroxide?
Magnesium hydroxide is favored as an antacid over sodium hydroxide because it has a lower risk of causing systemic alkalosis when used in moderate doses. Additionally, magnesium hydroxide can also act as a laxative, providing additional benefits for individuals with constipation. Sodium hydroxide, on the other hand, is a strong base that can lead to complications if ingested in significant amounts.
