Starting copper solution was too concentrated

Reference no: EM13709470

Problem- An acceptable (reliable) range of %T readings is 10%-90%. Suppose your starting copper solution was too concentrated to give a reliable reading on the spectrophotometer. Would it give a reading that was too high or too low (compared with the acceptable range of %T values)? Describe a way to correct this problem without dissolving a new piece of copper wire.

Explain each and every step in detail. I need proficient help in the above problems.
