Two numbered, unlabeled tubes contain a solution of potassium nitrate and potassium chloride. How can these substances be identified? Write the reaction equations in molecular, full ionic and abbreviated ionic forms.
It is necessary to add a solution of silver nitrate to each tube. In the test tube where a white precipitate will fall out, there is a solution of potassium chloride.
KCl + AgNO3 → AgCl ↓ + KNO3 (molecular form of the equation).
K + + Cl- + Ag + + NO3 – → AgCl ↓ + K + + NO3- (full ionic form of the equation).
Cl- + Ag + → AgCl ↓ (abbreviated ionic form of the equation).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
