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.
When limestone dissolves what happenns to the dissolved material?
When limestone dissolves, the dissolved material forms ions, primarily calcium and bicarbonate ions, in the water. These ions can then be carried away by the water through rivers or groundwater. Over time, this process can lead to the formation of caves and sinkholes.
What can you find dissolved in large quantities in hard water?
Calcium and magnesium are typically found dissolved in large quantities in hard water. These minerals can cause a buildup of scale in pipes, appliances, and fixtures over time.
Name two compounds which are covalent when pure but ionise to give ions when dissolved in water?
Hydrogen chloride and hydrogen fluoride are two examples of compounds that are covalent when pure but ionize to give ions when dissolved in water. When dissolved in water, hydrogen chloride forms H+ and Cl- ions, and hydrogen fluoride forms H+ and F- ions.
Does the hardness of water depend upon the metal or non metal ion of the mineral?
The hardness of water is primarily determined by the presence of dissolved calcium and magnesium ions in the water. These ions form insoluble precipitates with soap, leading to reduced lathering. The type of metal or non-metal ion in the mineral does influence water hardness, but calcium and magnesium ions are the main contributors.
Is calcium chloride dissolved in water an electrolyte or nonelectrolyte solution?
Calcium chloride dissolved in water is an electrolyte solution. When calcium chloride is dissolved, it dissociates into calcium ions (Ca²⁺) and chloride ions (Cl⁻), which are capable of conducting electricity in the solution.
What ions are present in hard water if it contains calcium chloride dissolved in distilled water?
In hard water containing calcium chloride dissolved in distilled water, the ions present would be calcium (Ca2+) and chloride (Cl-). The calcium ions come from calcium chloride, while the chloride ions come from the dissociation of calcium chloride in water.
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.
Is calcium hydrogencarbonate insoluble or soluble in water?
Calcium hydrogen carbonate is soluble in water. It dissociates into calcium ions (Ca²⁺) and bicarbonate ions (HCO₃⁻) when dissolved in water.
Is calcium bromide an electrolyte?
Yes, calcium bromide is an electrolyte. When dissolved in water, it dissociates into calcium ions (Ca²⁺) and bromide ions (Br⁻) which can conduct electricity.
When calcium chloride is dissolved in water will it conduct electricity?
Yes, calcium chloride dissociates into calcium ions (Ca^2+) and chloride ions (Cl^-) when dissolved in water. These ions are charged particles that can carry electric current, allowing the solution to conduct electricity.
What elements make up calcium hydrogen carbonate?
Calcium hydrogen carbonate is composed of calcium ions (Ca^2+), hydrogen carbonate ions (HCO3^-), and water molecules (H2O). When dissolved in water, calcium hydrogen carbonate dissociates to form these ions.
Is calcium hydroxide a weak electrolyte?
No, calcium hydroxide is a strong electrolyte. When dissolved in water, it completely dissociates into calcium ions (Ca2+) and hydroxide ions (OH-), resulting in a high degree of conductivity.
Number of ions in solubility of calcium chloride?
Calcium chloride, CaCl2, dissociates in water to form three ions: one calcium ion (Ca2+) and two chloride ions (2Cl-). So for every formula unit of calcium chloride dissolved in water, it produces three ions in solution.
Is calcium chloride a good conductor of electricity?
Yes, calcium chloride is a good conductor of electricity when dissolved in water. The dissolved ions in calcium chloride allow the flow of electric current through the solution. However, solid calcium chloride is not a good conductor of electricity because it does not contain free-moving ions.
Why aqueous solution of oxide of calcium is basic?
Aqueous solutions of calcium oxide (CaO) are basic because they produce hydroxide ions when dissolved in water. Calcium oxide reacts with water to form calcium hydroxide, which dissociates to release hydroxide ions, increasing the pH of the solution and making it basic.
Does calcium chloride conduct electricity in water?
Yes, calcium chloride can conduct electricity in water because it dissociates into ions (calcium and chloride ions) when dissolved. These ions are free to move in the water, allowing them to carry an electric charge and conduct electricity.
