Given below are two statements:
Statement I: Aqueous solution of K$$_2$$Cr$$_2$$O$$_7$$ is preferred as a primary standard in volumetric analysis over Na$$_2$$Cr$$_2$$O$$_7$$ aqueous solution.
Statement II: K$$_2$$Cr$$_2$$O$$_7$$ has a higher solubility in water than Na$$_2$$Cr$$_2$$O$$_7$$. In the light of the above statements, choose the correct answer from the options given below:

Statement I: K₂Cr₂O₇ is preferred as a primary standard over Na₂Cr₂O₇.

This is true. K₂Cr₂O₇ is non-hygroscopic and can be obtained in a highly pure state, making it suitable as a primary standard. Na₂Cr₂O₇ is hygroscopic.

Statement II: K₂Cr₂O₇ has higher solubility than Na₂Cr₂O₇.

This is false. Na₂Cr₂O₇ is actually more soluble in water than K₂Cr₂O₇.

The correct answer is Option 3: Statement I is true but Statement II is false.
