Compute the pH of the titration solution before any acid is added, when the titration is 1.00 mL short of the equiv- alence point, when the titration is at the equivalence point, and when the titration is 1.00 mL past the equivalence point. (Note: Each mole of Ba(OH)2 gives two moles of OH2 in solution.)
Answers
answer: c. the experiment shows that the red substance experienced a chemical change.
explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.
chemical changes are accompanied by following changes:
a) precipitate formation
b) energy is released or absorbed
c) formation of bubbles
d) change in color
as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
e
d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
