Based on the cations identified in the question above, determine if the painting in question was a forgery. Explain how you were able to determine if the painting was a forgery. Indicate which pigments were likely in the unknown and when they were likely used. Note that each cation itself is not a pigment; the full chemical formula for each pigment can be found in the Pigment Handbook in your lab manual.

where's the diagram?

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
