Avariety of procedural errors can impact the effectiveness of the copper reaction cycle. comment on the following documented errors: a. when naoh (aq) is added to the cu(no3)2 solution in reaction b, the cu(oh)2 (s) occasionally does not precipitate immediately, and excess naoh must be added. what other substance present in the reaction mixture might preferentially react with the naoh and prevent precipitation of the cu(oh)2? explain.

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.
