A salt with few drops of conc. \( \text{HCl} \) gives apple green colour in flame test. The group precipitate of the salt is dissolved in acetic acid and treated with \( \text{K}_2\text{CrO}_4 \) to give yellow precipitate. When the sodium carbonate extract of the salt solution is heated with conc. \( \text{HNO}_3 \) and ammonium molybdate, it resulted a canary yellow precipitate. The cation and anion present in the salt are respectively,

Given below are two statements:
Statement I: Sodium dichromate and potassium dichromate are classified as primary standards in titrimetric analysis.
Statement II: Phenolphthalein is a weak base, therefore it dissociates in acidic medium.
In the light of the above statements, choose the correct answer from the options given below

On heating a mixture of common salt and \( \text{K}_{2}\text{Cr}_{2}\text{O}_{7} \) in equal amount along with concentrated \( \text{H}_{2}\text{SO}_{4} \) in a test tube, a gas is evolved. Formula of the gas evolved and oxidation state of the central metal atom in the gas respectively are:

Consider three metal chlorides \( x \), \( y \) and \( z \), where \( x \) is water soluble at room temperature, \( y \) is sparingly soluble in water at room temperature and \( z \) is soluble in hot water. \( x \), \( y \) and \( z \) are respectively:

In sulphur estimation, \( 2.0 \times 10^{-3} \) mol of an organic compound \( (X) \) \( (\text{molar mass } 76 \, \text{g mol}^{-1}) \) gave \( 0.4813 \, \text{g} \) of barium sulphate \( (\text{molar mass } 233 \, \text{g mol}^{-1}) \). The percentage of sulphur in the compound \( (X) \) is ______ \( \times 10^{-1}\% \).
