When creating the Academic Database, there were several instances of data validation. Data types were assigned to each field in the table to stop undesirable values from being placed into certain fields. A presence check was used on fields that were listed as NOT NULL, requiring some data to be input. Uniqueness validation was automatically assigned for fields that were primary keys. Describe at least one field in the Academic Database a table where range validation could have been used and describe at least one field in the Academic Database where choice validation could have been used. Your answer should be addressed in 100 to 150 words.

Question 40.5 pts Redox reactions during Qualitative Analysis. Likewise, there were several instances during the Qual procedure where a redox reaction occurred (which often was also associated with a change in solubility). During the cation procedure, adding a mixture of H2O2 and NaOH caused Cr(OH)3 to be converted to CrO42–. Not accidentally, one of these compounds was quite insoluble while the other one was quite soluble. The balanced reaction equation is: 2 Cr(OH)3(s) + 3 H2O2(aq) + 4 OH–(aq) →...
