What substance adds or removes Hydrogen ions from a solution?
metals and salts that precipitate it - e.g silver nitrate would remove OH ions from solution. Acids would also tend to remove OH ions from solution
What happens when magnesium metal is added to an aqueous solution of aluminium ions?
Magnesium acts as an oxidant when added to the aluminum ions, and consquently it will oxidize the aluminum and take it out of the solution forming aluminum solid and then the mangesium itself will go into the solution since it will be oxidezed by the aluminum. The equation would be: Mg (s) + Al³⁺ (aq) → Mg²⁺ (aq) + Al (s)
What is the dissociation of cobalt II nitrate?
Cobalt(II) nitrate dissociates as follows:Co(NO3)2 ==> Co^2+ + 2NO3^-
How many ions are in sulfate in Al2SO4?
There are 3 ions in the formula Al2SO4 (2 aluminum and 1 sulfate), but this formula is wrong. The formula of aluminum sulfate is Al2(SO4)3 which contains 5 ions: 2 aluminum ions and 3 sulfate ions.
How are aluminum ions joined together to form a can?
electrons are shared between all aluminum ions in the bar

What is the symbol for aluminum iodide?
AI Aluminum iodide: The chemical formula is AlI3 In solution 4 ions: Al3+ an 3 I- (iodide)

What are substances that remove H from a solution?
A compound that accepts ("removes") hydrogen ions in a solution is a base.
What kind of ions does cobalt make?
Cobalt is an element, and therefore it is not made out of ions, although it can be ionized. Like all metals, cobalt forms positive ions (by losing electrons).
What is the dissociation of cobalt II nitrate?
Cobalt(II) nitrate dissociates as follows:Co(NO3)2 ==> Co^2+ + 2NO3^-

What is the charge of ions of aluminum?
Aluminum has trivalent cation. It is Al3+
If a solution is acidic it has how many ions?
If a solution is basic it has how many ions
Does cobalt become a charged ion?
All atoms (other than Noble Gases) can become ions, and all ions are charged. Cobalt gains a charge of +2 as an ion.
Do soluble salts show any colour in aqueous state?
Most of them don't, but some do give color in aquous solution, eg. copper(II) ions are blue, iron(III) = ferric ions are pale green, cobalt rose colored, KMnO4 solution is very dark purple (potassium permanganate)
