I'm interested in increasing the number of analog in pins on my Arduiono Uno. Would the general purpose ports added by the MCP23017 - i2c 16 be able to use the analogRead() function?

Can the MCP23017 expand Analog In pins?

No. That is a digital only device. To extend your analog capabilities, you can use:
