I can tell only few
sulphuric acid is called king of all chemical because it is very strong acid
the curd should not be kept in copper or brass vessel because it reacts with copper and brass and become poisonous
NAOH contains hydrogen ions but it also contains oxygen we basic means it contains hydroxide so NAOH is basic
rain water contains electricity because it has ions where distilled water does not have any ions so it doesn't contain electricity
