To afford cathodic protection to an iron object, a metal must be to reduce (have a more reduction potential) than F e 2 + .

The E r e d ∘ for C d 2 + is , while the E r e d ∘ for F e 2 + is . Therefore, the coating of cadmium protect iron by cathodic protection.

What is driving behind plate tectonics (plate movment)? a) gravity only b) inertia c) convection and gravity d) the sun theres no option for science so i picked chemistry. plz

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

In salt water solution, the salt is the blank
