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.

its going to be mutualism cuz they both benefit from the relationship.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
