Another metal phosphate is aluminum phosphate. It will behave similar to calcium phosphate in an acid solution. What is the net ionic equation including phases for AlPO4(s) dissolving in H3O+(aq)? Assume that metal phosphate and hydronium cations react reversibly in a 1:1 ratio.

AlPO4(s) + H3O+(aq) > Al3+(aq) + HPO4^2-(aq) + H2O(l)

Explanation:

The net ionic equation for the reaction between aluminum phosphate and hydronium ion shown below.

AlPO4(s) + H3O+(aq) > Al3+(aq) + HPO4^2-(aq) + H2O(l)

Note H3O+(aq) comes from an acid. The acid is required to keep the Al3+(aq) in aqueous solution. If not, it will precipitate as Al(OH)3.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
