How many ions present in NaCl solution?
In a NaCl (sodium chloride) solution, there are two types of ions present: sodium ions (Na+) and chloride ions (Cl-). This is because when NaCl dissolves in water, it dissociates into these two ions, which are responsible for conducting electricity in the solution.
How can you test a solution for the barium ions?
Acidify the given solution with a few drops of concentrated HNO3 followed by the addition of 4 mol dm-3 sulphuric acid or ammonium sulphate. A white precipitate implies that there are Barium (II) ions present in the solution. The objective of the test give above is to recognize the Barium(II) ions as the white precipitate of barium sulphate which is not soluble in most of the solvents. Adding a sulphate solution at first might cause distractions as other cations such as strontium also make white precipitates with sulphate ions. Those other precipitates dissolve in dilute nitric acid.
How many sodium ions are present in 325 mL of 0.850 M Na2SO4?
There are 0.850 moles of Na2SO4 in 325 mL of 0.850 M solution. Since Na2SO4 contains 2 sodium ions per formula unit, there will be 2*0.850 moles of sodium ions in the solution. Thus, there are 1.7 moles of sodium ions in 325 mL of 0.850 M Na2SO4 solution.
What species are present when sodium carbonate is placed in water?
When sodium carbonate is placed in water, it dissociates to form sodium ions (Na+) and carbonate ions (CO3^2-). These ions attract water molecules and hydrate, hence the presence of sodium ions and carbonate ions in solution.
What are the ions in sodium chloride solution?
In a sodium chloride solution, the ions present are sodium cations (Na+) and chloride anions (Cl-). When NaCl dissolves in water, it dissociates into these ions, which are responsible for the solution's conductivity and other properties.
Where does the sodium sulphate go when copper sulphate mixes with sodium hydroxide?
Nowhere. I assume you are talking about mixing solutions. The sodium ions and sulpahate ions remain in solution.
Why does strontium sulfate becomes less soluble in an aqueous solution when sodium sulfate is added?
Sodium sulphate increases the concentration of sulphate ions. So strontium sulphate solubility decreases.
Does sodium nitrate solution with dilute hydrochloric acid make sodiumsulphate?
How it is possible ? both reagent do not contain sulphate ions, sulphuric acid may form sodium sulphate with sodium nitrate.
How many ions present in NaCl solution?

How do you test for sulphate ions?
add barium chloride or barium nitrate to a solution containing sulphate ions SO4 2-. To the same solution add hydrochloric acid in excess. OBSERVATIONS, a white precipitate which is insoluble in excess acid confirms presence of SO42- IF IT DISSOLVES then it confirms SO32- ----------------------------------------- 1) Add barium nitrate solution under acidic conditions (use an equal volume of hydrochloric acid) to the unknown solution 2) A white precipitate of barium sulphate forms if sulphate ions are present
What is the pH of sodium sulphate?
The pH of a sodium sulfate solution is typically neutral, around 7, since sodium salts are made up of ions that do not affect the pH significantly.
Write the ions present in solution of Na3PO4?
The ions that are present in the solution of sodium phosphate is the sodium ions and the phosphate ions. The sodium ion has +3 charge while the phosphate ion has the -3 charge.
When sodium sulfate dissolves in water what ion would be present in the solution?
When sodium sulfate dissolves in water, it dissociates into sodium ions (Na⁺) and sulfate ions (SO₄²⁻). These ions would be present in the solution along with water molecules.
What is the type of particle of sodium sulphate?
Sodium sulphate is an ionic compound composed of sodium ions (Na+) and sulphate ions (SO4^2-). It is not a single particle but a crystalline solid made up of a repeating pattern of these ions.
What is the ionic species present in an aqueous solution in sodium chloride?
In an aqueous solution of sodium chloride (NaCl), the ionic species present are sodium ions (Na+) and chloride ions (Cl-). Sodium chloride dissociates into its ions when dissolved in water, leading to the formation of these two ionic species.

When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
