25.00 mL of a H2SO4 solution with an unknown concentration was titrated to a phenolphthalein endpoint with 33.67 mL of a 0.1317 M NaOH solution.
What is the concentration of the H2SO4 solution?

h let me think

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

out of these options:

ability to burn paper

pure sodium reacting violently with water

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
