Comparing methods

[EspoirTron]

Hi

So basically I was wondering if anyone could compare the following analytical techniques for me, highlighting each one's pros and cons.
Gravimetric analysis, volumetric analysis (acid-base titration), redox titrations and UV-Visible spectroscopy. If someone could please tell me the main flaws in each and how each one is beneficial it would be greatly appreciated and if anyone could support those theories with chemical equations it would be brilliant.

Thanks

Gravimetric analysis and volumetric analysis
Pros

• Cheaper in the short term

Cons

• Slow
• More expensive in the long term- labour costs

UV-Visible spectroscopy
Pros

• Fast
• Very sensitive

Cons

• High initial cost- equipment

Thanks for that! 
Also though when we talking about analysis techniques, what flaws are there in gravimetric analysis besides co-precipitation? Like those forms of flaws, I understand the economical factors but I am more wanting to know the flaws behind the key theories and the loop holes in each if you would know them, I would greatly appreciate if you could share them?

Are you asking about potential errors that could occur in gravimetric analysis?

[EspoirTron]

Yes essentially, both human related and experimental errors that could occur across all four forms of analysis?

[Bad Student]

In all forms of analysis, the equipment used carries built-in uncertainty. The equipment used in volumetric and gravimetric analysis are less precise than the equipment used in instrumental analysis.

In volumetric analysis, errors can come from washing the equipment with the wrong solution.

In gravimetric analysis, errors can come from the compound not fully precipitating and other unwanted compounds precipitating.

Thank you for that, I appreciate your help!
