Given below are two statements:
Statement I: Aqueous solution of \(\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}\) is preferred as a primary standard in volumetric analysis over \(\mathrm{Na}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}\) aqueous solution.
Statement II: \(\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}\) has a higher solubility in water than \(\mathrm{Na}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}\)
In the light of the above statements, choose the correct answer from the options given below:
