Is CaO is a base compound?
CaO (calcium oxide) is considered a base compound because it reacts with water to form a basic solution (calcium hydroxide). It can neutralize acids to form salts and water.
How soluble is calcium nitrate in water?
The solubility of calcium nitrate in water at 20 0C is very high: 1 212 g/L.
Does the mass of calcium oxide effect the temperature rise when calcium oxide reacts with water?
No, the mass of calcium oxide does not affect the temperature rise when it reacts with water. The temperature rise is determined by the amount of energy released during the exothermic reaction between calcium oxide and water, which is constant regardless of the mass of calcium oxide used.
Why does calcium nitrate have a high conductivity?
Calcium nitrate is a salt that dissociates into calcium and nitrate ions when dissolved in water. These ions are free to move and carry electric charge, leading to high conductivity. Additionally, calcium nitrate is highly soluble in water, which further enhances its conductivity.
How much elemental Calcium is there in Calcium oxide?
There is no elemental calcium in calcium oxide. Calcium oxide is a compound made up of calcium and oxygen atoms bonded together. When calcium oxide reacts with water, it forms calcium hydroxide, which contains calcium ions but not elemental calcium.
Is calcium oxide an acid or base?
Calcium oxide (CaO) is a basic oxide, also known as a metal oxide. When calcium oxide is dissolved in water, it reacts to form calcium hydroxide, which is a strong base. The basic nature of calcium oxide is due to its ability to donate hydroxide ions (OH-) in solution, making it a base rather than an acid.
Calcium oxide plus nitric acid?
you get carbon dioxide if you mix any acid with a carbonate aswell as water and calcium nitrate. 2HNO3(aq) + CaCO3(s) = Ca(NO3)2(s) + H2O(l) + CO2(g) Ca is a 2+ ion, and the NO3 is only a - ion, therefore two are needed! this balances the equation.
What is the word equation of calcium oxide and water?
Calcium oxide and Water = Calcium hydroxide(Slaked lime/ lime water). . Here is the BALANCED reaction equation CaO(s)+ H2O(l) = Ca(OH)2(aq)
Is calcium nitrate soluble in water?
Yes, calcium nitrate is highly soluble in water. It readily dissociates into calcium ions and nitrate ions when dissolved in water.
Does calcium nitrate dissociate in water?
Yes, calcium nitrate does dissociate in water to form calcium ions (Ca²⁺) and nitrate ions (NO₃⁻). This dissociation process allows the ions to be mobile in solution, making calcium nitrate a soluble compound.
Will calcium nitrate lower the pH in water?
No, calcium nitrate will not lower the pH in water. In fact, it may slightly increase the pH because calcium nitrate is a neutral salt that can act as a buffer in water.
What is the word equation for calcium oxide?
The word equation for calcium oxide is: calcium oxide + water → calcium hydroxide.
What happens when mixing calcium nitrate in water compound?
When calcium nitrate is mixed in water, it dissociates into its ions: calcium (Ca2+) and nitrate (NO3-). These ions remain in solution and are free to interact with other substances present in the solution. The solution will also undergo an endothermic process as the dissolution of calcium nitrate in water absorbs heat from the surroundings.
What does hydrochloric acid and calcium oxide make?
Calcium + water. Chloride Since it is a neutralisation reaction: Acid + metal oxide = salt + water Hydrogen Calcium Calcium Water Chloride + Oxide = Chloride +
Is CaO is a base compound?
CaO (calcium oxide) is considered a base compound because it reacts with water to form a basic solution (calcium hydroxide). It can neutralize acids to form salts and water.
What is the WORD equation for the reaction between calcium oxide and water?
This chemical reaction is: CaO + H2O = Ca(OH)2.
Word Equation for magnesium oxide and nitric acid?
Magnesium Oxide + Nitric Acid -----> Magnesium Nitrate + Water. Hope this helps.
