Sodium will be positive.
Check your Periodic Table; all those elements on the left will always be positive ions.
What else can I help you with?
Is silver nitrate a positive ion or negative ion?
Silver nitrate (AgNO3) contains a positive silver ion (Ag+) and a negative nitrate ion (NO3-). Silver ion is positively charged because it has lost one electron, while the nitrate ion is negatively charged due to its structure.
Is sodium nitrate homogeneous?
Yes, sodium nitrate is a homogeneous substance. It is a compound formed by the combination of sodium ions and nitrate ions, resulting in a uniform composition throughout the material.
Reaction of sodium iodide with silver nitrate?
When sodium iodide reacts with silver nitrate, a double displacement reaction occurs. The sodium ions exchange with the silver ions, forming silver iodide as a white precipitate and sodium nitrate. This reaction can be represented by the equation: 2NaI + 2AgNO3 → 2AgI + 2NaNO3
Sodium hydroide completely dissociates into positive and negative ions and is therefore a?
Strong base
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 force would you expect between sodium ions and chloride ions in a crystal of sodium chloride?
(+)--(-) positive and negative
Why are sodium ions and chloride ions attracted to each other?
Sodium ions have a positive charge, while chloride ions have a negative charge. Opposite charges attract, so the positive sodium ions are attracted to the negative chloride ions. This attraction leads to the formation of an ionic bond between sodium and chlorine, resulting in the creation of sodium chloride or table salt.
Is silver nitrate a positive ion or negative ion?
Silver nitrate (AgNO3) contains a positive silver ion (Ag+) and a negative nitrate ion (NO3-). Silver ion is positively charged because it has lost one electron, while the nitrate ion is negatively charged due to its structure.
What compounds are produced when sodium nitrate is added to a mixture of water and ethanol?
When sodium nitrate is added to a mixture of water and ethanol, it dissociates into sodium ions and nitrate ions. No new compounds are formed.
Is sodium chloride a good conductor of electricity when melted?
Yes. It forms sodium positive ions (cations) and negative chloride ions (anions).
Which ions are formed when sodium sulfate and silver nitrate are dissolved in water?
Hydrated sodium, sulfate, silver, and nitrate ions. (The ions already exist in the sodium sulfate and silver nitrate solids, but may not be hydrated there.) since silver sulfate is not very soluble in water, most of the silver and sulfate ions will be removed from the water as solid precipitate, but some hydrated ions will remain in solution.
What types of ions are presented in salt?
In salt, the common types of ions present are sodium (Na+) and chloride (Cl-). Sodium carries a positive charge, while chloride carries a negative charge, forming an ionic bond that makes up salt crystals.
What ions are formed when sodium nitrate compounds dissolve in water?
When sodium nitrate dissolves in water, it dissociates into sodium ions (Na+) and nitrate ions (NO3-). These ions remain solvated in the water solution due to the attraction between the ions and the polar water molecules.
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 holds the ions in sodium chloride together?
The ions in sodium chloride are held together by ionic bonds. In this type of bond, the positive sodium ions are attracted to the negative chloride ions, creating a strong electrostatic force that keeps the ions together in a crystal lattice structure.
Is sodium nitrate homogeneous?
Yes, sodium nitrate is a homogeneous substance. It is a compound formed by the combination of sodium ions and nitrate ions, resulting in a uniform composition throughout the material.
What happens sodium chloride dissolves in water?
It separates into positive sodium and negative chloride ions.
