Is cerium active?
It is reasonably reactive. It has been used as a drier for alkyd paints. In that form it was Cerium Octoate.
How do prepare hard water?
To prepare hard water, simply dissolve calcium and magnesium salts like calcium chloride or magnesium sulfate in regular water. The concentration of these salts determines the hardness of the water. The dissolved salts will increase the mineral content of the water, making it hard.
What mass of calcium bromide is needed to prepare 250 ml of a 2.50M?
The answer is 124,93 g (for the anhydrous CaBr2).
How can you prepare flocculated suspension?
To prepare a flocculated suspension, you can use flocculating agents such as electrolytes (e.g. calcium chloride or aluminum sulfate) or polymers. Add the flocculating agent to the suspension slowly while stirring to promote the aggregation of particles. Adjust the pH if needed to optimize flocculation.
What uses nitric acid making paper making paint or making fertilizers?
Nitric acid is largely used to prepare ammonium and calcium nitrate, common fertilizers for agriculture.
Is cerium active?
It is reasonably reactive. It has been used as a drier for alkyd paints. In that form it was Cerium Octoate.
How can you separate calcium oxide to its components?
By the reduction of calcium oxide you can prepare calcium: CaO + Mg = Ca + MgO 3CaO + 2Al -> Al2O3 + 3Ca
Would you prepare calcium oxalate precipitate in a acidic or basic solution?
You would typically prepare calcium oxalate precipitate in a slightly acidic solution. This helps to keep the oxalate ions stable and ensure proper precipitation of the calcium oxalate compound.
Is calcium in vitamin c?
No calcium is in pure vitamin C. It is possible a manufacture may prepare the calcium salt of vitamin C in its formulation. The label would indicate that.
What mas of calcium bromide is needed to prepare 150.0ml of a 3.50M solution?
105 g
Is calsuim hydroxide another name for lime water and how do you prepare it?
Yes it is but it is calcium with a c
How do prepare hard water?
To prepare hard water, simply dissolve calcium and magnesium salts like calcium chloride or magnesium sulfate in regular water. The concentration of these salts determines the hardness of the water. The dissolved salts will increase the mineral content of the water, making it hard.
Why is lime used compare to other substances?
Limestone is widely used to prepare cement, calcium hydroxide or as building material.
What is the most important factor in decreasing intracellular concentration of calcium ion after contraction is?
The most important factor in decreasing intracellular calcium ion concentration after contraction is the active transport of calcium ions out of the cell by the calcium ATPase pump located on the cell membrane. This pump helps in restoring the calcium ion concentration back to its baseline level, allowing the muscle to relax and prepare for the next contraction.
How do you prepare ethyl methyl ketone from calcium acetate?
Ethyl methyl ketone can be prepared from calcium acetate by reacting it with barium hydroxide to form barium acetate, which can then be treated with sulfuric acid to yield ethyl methyl ketone. The ketone can be further purified by distillation.
What mass of calcium bromide is needed to prepare 250 ml of a 2.50M?
The answer is 124,93 g (for the anhydrous CaBr2).
Chemical reaction in the preparation of citric acid from calamansi?
To prepare citric acid from calamansi, the main chemical reaction involved is the conversion of citric acid in the fruit juice to its calcium citrate salt. This reaction occurs when calcium hydroxide is added to the calamansi juice, resulting in the formation of insoluble calcium citrate precipitate. The precipitate is then filtered and treated with sulfuric acid to regenerate citric acid in its pure form.
