IF `C_2H_5 OH and H_2O` solution is example of non-ideal solution then which graphically representation is correct?

When the compounds CH_3COOH, C_2H_5OH and C_6H_5OH are arranged in order of increasing acidity in aqueous solution, which order is correct?

What is the molality of C_2H_5 OH in water solution which will freeze at -10^@C ?

CoCl_(3).4H_(2)O is an anyhydrous binary solute hence its Werner's representation is :

A Solution of C_(2)H_(5)OH and water contains 54% water by mass, then which option(s) are correct for the given solution: [Given density of solution =1 gm/ml]

For a non-ideal solution, Delta_(mix)V and Delta_(mix)H are zero.

A fresh H_(2)O_(2) solution is labelled 11.2V . This solution has the same concentration as a solution which is

34 g of H_(2)O_(2) is present in H_(2)O mL of solution. This solution is called.
