When CaCl2 is dissolved in water how many ions does it have?
When CaCl2 is dissolved in water, it forms three ions in total: one Ca2+ ion and two Cl- ions.
What happens when FeCl3 is dissolved in water?
When FeCl3 is dissolved in water, it dissociates into Fe3 ions and Cl- ions. This forms a solution that is yellow-brown in color due to the presence of the Fe3 ions.
What happens when FeCl2 is dissolved in water?
When FeCl2 is dissolved in water, it dissociates into Fe2 ions and Cl- ions. This forms a solution that conducts electricity and has a yellow-green color.
What forms hydrogen ions when dissolved in water?
When acids dissolve in water, they dissociate to form hydronium ions. There is not a substance that's forms truly forms hydrogen ions in water.However, for purposes of convenience the hydronium ions are sometimes referred to as hydrogen ions.
If a substance dissociates and forms an excess of h positive ions when dissolved in watr it is referred to as?
If a substance dissociates and forms an excess of H+ ions when dissolved in water, it is referred to as an acid. Acids are substances that donate protons when dissolved in water, leading to an increase in H+ ions concentration in the solution.
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.
Is ammonia soluble?
Yes, ammonia is soluble in water. It forms ammonium ions (NH4+) and hydroxide ions (OH-) when dissolved in water.
When a compound that forms metals and nonmetal ions when dissolved in water is called a?
it is called an electrolyte!
What happen when cupper sulphate dissolved in water?
When copper sulfate is dissolved in water, it dissociates into copper ions (Cu2+) and sulfate ions (SO4^2-). This forms a blue solution due to the presence of the copper ions. Additionally, the sulfate ions remain in solution and do not react with water.
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 would be formed when sodium chloride is dissolved in water?
When sodium chloride is dissolved in water, it dissociates into sodium ions (Na+) and chloride ions (Cl-). This forms a solution of sodium chloride where the ions are free to move and conduct electricity.
Do acids create hydroxide ions when dissolved in water?
No, acids do not create hydroxide (OH-) ions when dissolved in water. Acids create Hydrogen (H+) ions when dissolved in water.Bases create hydroxide ions when dissolved in water.
