Astudent tests two solutions with the same acid-base indicator. if the two solutions have different hydroxide ion concentrations, which would you expect to be true?
a)the two solutions will have identical hydrogen ion concentrations.
b)the indicator will be the same color in both solutions.
c)the indicator will have different colors in the different solutions.
d)the two solutions will react to produce a salt and water.

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
