What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
What happens when sodium ions come in contact with the negative electrode in a cell used for electrolysis?
the world end
Is sodium hydroxide a strong alkali?
Yes, it dissociates completely into lithium and hydroxide ions.
Sodium hydroxide potassium hydroxide and magnesium hydroxide all produce hydroxide ions in water and are therefore?
bases
What happens when you add sodium hydroxide to copper bromide?
When you combine these substances, a metathesis reaction occurs. In this reaction, copper becomes bonded to hydroxide ions. Because copper hydroxide is insoluble, it precipitates out of solution.
What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
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

Does sodium hydroxide release protons when added to water?
No. Sodium hydroxide releases hydroxide ions, which actually take protons out of the solution. This qualifies sodium hydroxide as a base.
What ions are present in an aqueous solution of potassium hydroxide?
When sodium hydroxide (NaOH) is dissolved in water, the ions formed are Na^+ and OH^-. Sodium hydroxide is a strong electrolyte and will ionized completely.
Sodium hydroxide dissolves in water is?
Sodium hydroxide disassociates in water into a solution of Na+ and OH- ions. Itis an exothermic reaction which gives out heat.
Why will molten Sodium Chloride undergo electrolysis?
Molten sodium chloride consists of sodium ions and chloride ions and is therefore a conductor of electricity- and can be electrlysed.
Is sodium hydroxide a strong alkali?
Yes, it dissociates completely into lithium and hydroxide ions.
Sodium hydroxide potassium hydroxide and magnesium hydroxide all produce hydroxide ions in water and are therefore?
bases
Chemical containing hydroxide ions?
sodium
Why does barium nitrate in sodium hydroxide form a precipitate?
In aqueous solution, barium nitrate and sodium hydroxide undergo a double replacement reaction, in which barium ions combine with hydroxide ions to form barium hydroxide and sodium ions combine with nitrate ions to form sodium nitrate. Barium hydroxide is insoluble in water, so it precipitates out of solution. Ba(NO3)2(aq) + 2NaOH(aq) --> Ba(OH)2(s) + 2NaNO3(aq)
What happens when you mix sodium hydroxide and sodium chloride?
Sodium chloride is dissolved in water and dissociated in ions.
