`{:(Column-I,Column-II),(10ml 0.1M NaOH" aqueous solution is",(p)"Osmotic pressure of solution INCREASES"):}`
`{:(Column-I,Column-II),( 10"ml 0.1MNaOH aqueous solution is",(q)"Vapour pressure of solutions increases"),("added to 10ml" 0.1M CH_(3)COOH "aqueous solution",):}`
`{:(Column-I,Column-II),(10 ml 0.1M HCI"aqueous solution",(r)"Boiling point of solution increases"),("added to 10 ml" 0.1M NH_(3)"aqueous solution",):}`
`{:(Column-I,Column-II),(10ml 0.1M HCI "aqueous solution to",(s)"Freezing point of solution increases"),(10 ml 0.1M KOH "aqueous solution",):}`

Solution :`{:(10mL,10mL,,),(0.1M,0.1M,,),(NaOH+,HCIrarr,NACI+,H_(2)O),(1m mol,1m mol,-,-),(,,,1m mol),((L=2),(L=2),C=(1)/(20)m mol//mL,),(,,(L=2),):}`
