EKB Knowledge Bank for Discovery of Cations and Anions in High School Chemistry (Part 1)





EKB Questions 
Detection of first and second group cations
Detection of third group cations
Detection of The Fifth Group Cations
Detection of the first group ions
Detection of second and third group enions
We have collected all the questions of the Egyptian EKB in detecting the irons and the anions in order to help you to meet all the questions on Title II
And to be ready for you to recalled and reviewed later 
We have made a great effort to gather these questions, so that we do not hesitate to share them and pray for us at the back of the unseen😘

Note: - The correct answers at the bottom 👇
