Karolínka with her mother preapred eperiment with black tea. They mixed in one vessel tea with lemon juice, tea become lighter. When they poured vinegar tea changed on little bit lighter than pure tea. For third vessel they puted baking soda. Tea changed colour for darkness, like a very strong tea.
Why?
Becouse vinegar and lemon juice is acid, when we poured them to a tea, they change themselve Ph, so they become a base, when we put baking soda to a tea, it change to a acid, because tea is dark.
