What ions form when sodium hydroxide dissolves in water?
When sodium hydroxide (NaOH) dissolves in water, it forms sodium ions (Na+) and hydroxide ions (OH-). The sodium ions are positively charged and the hydroxide ions are negatively charged.
What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
What happens to Copper sulfate and sodium hydroxide when mixed together?
When copper sulfate and sodium hydroxide are mixed together, a double displacement reaction occurs. The copper ions from copper sulfate react with hydroxide ions from sodium hydroxide to form a blue precipitate of copper hydroxide. The resulting solution will contain sodium sulfate.
Industrial preparation of NaOH with diagram?
The industrial preparation of sodium hydroxide (NaOH) is commonly done through the chloralkali process, where a concentrated solution of sodium chloride (brine) is electrolyzed to produce chlorine gas, hydrogen gas, and sodium hydroxide. The diagram would typically show an electrolysis cell with an anode, a cathode, and a brine solution. The anode oxidizes chloride ions to produce chlorine gas, while the cathode reduces water to hydrogen gas and hydroxide ions, which then combine to form sodium hydroxide.
Is sodium hydroxide a homogeneous mixture?
No, sodium hydroxide is a pure compound, not a mixture. It is a strong base made up of sodium ions (Na+) and hydroxide ions (OH-).

Is sodium hydroxide obtained from rock salt?
Sodium hydroxide is obtained from salt, yes. The manufacture of this strong base is accomplished mainly from what is termed the chloralkali process. This is the electrolysis of a salt solution which produces sodium hydroxide and also chlorine and hydrogen gas. It is an industrial process that is important to the chemical industry. A link follows.
What happens in the reaction between sodium hydroxide and magnesium sulphate?
When sodium hydroxide reacts with magnesium sulfate, a double displacement reaction occurs where the sodium ions from sodium hydroxide switch places with the magnesium ions from magnesium sulfate to form sodium sulfate and magnesium hydroxide. The products of this reaction are aqueous sodium sulfate and a white precipitate of magnesium hydroxide.
What happens to Copper sulfate and sodium hydroxide when mixed together?
When copper sulfate and sodium hydroxide are mixed together, a double displacement reaction occurs. The copper ions from copper sulfate react with hydroxide ions from sodium hydroxide to form a blue precipitate of copper hydroxide. The resulting solution will contain sodium sulfate.
Chemical containing hydroxide ions?
One example of a chemical containing hydroxide ions is sodium hydroxide, which has the chemical formula NaOH. When dissolved in water, sodium hydroxide dissociates into sodium ions (Na+) and hydroxide ions (OH-). Hydroxide ions are strong bases and can react with acids to form water and a salt.
When electrolysis occurs in salt water chlorine and hydrogen are given off what happens to the sodium and oxygen?
The electrolysis of brine (salt solution) involves the breakdown of sodium chloride and water into its basic ionic components: sodium, hydrogen, chlorine and hydroxide ions. The hydrogen and sodium are both positively charged ions, and are attracted towards the negatively charged electrode, where the least reactive of the two ions - hydrogen - gains an electron to become an uncharged hydrogen atom. Sodium is more reactive, so it remains in the electrolysis chamber (sometimes called a diaphragm cell) as an Na+ ion. The chloride and hydroxide ions are negatively charged, so they are attracted to the anode, where the chloride is liberated as a chlorine molecule, because it is the least reactive of the two anions. The hydroxide remains in the container as an OH- ion. The chlorine is used to sterilise swimming pools and to make PVC plastics. The hydrogen is used in the process of making margarine. Meanwhile the sodium and the hydroxide ions join together to form sodium hydroxide, which is a widely used bleach. It is also used in the manufacture of paper and soap. The equation for the electrolysis of brine is: 2NaCl + 2H2O --------> Cl2 + H2 + NaOH
What happens at the anode and cathode in the electrolysis of brine?
In the electrolysis of brine (saltwater), at the anode, chloride ions (Cl⁻) are oxidized to form chlorine gas (Cl₂). At the cathode, water molecules are reduced to produce hydrogen gas (H₂) and hydroxide ions (OH⁻). This process results in the formation of chlorine gas at the anode and hydrogen gas at the cathode, with sodium hydroxide (NaOH) remaining in the solution.

What happens when sodium ions come in contact with the negative electrode in a cell used for electrolysis?
When sodium ions come in contact with the negative electrode in a cell used for electrolysis, they accept electrons and get reduced to form sodium metal. This process occurs as part of the overall electrolysis reaction, where positive ions are reduced at the negative electrode while negative ions are oxidized at the positive electrode.
What ions does Na OH form when placed in water?
When NaOH (sodium hydroxide) is placed in water, it forms sodium ions (Na+) and hydroxide ions (OH-). Sodium ions are positively charged and hydroxide ions are negatively charged.
