1.	Among the following (a)On dilution the P^(H)of an acid increases (b)A solution with P^(H)= 5 is 100 times more basic than a solution withp^(H)=3(3)A solution with P^(H)=8 is 1000 times more acidic than a solution with P^(H)=11 (4)The P^(H)of 10 ^(-9)M KOH is slightly greater than
Answer» All are correct 1, 4 are only correct 1,2,3 are only correct All are WRONG SOLUTION :on dilution , pH increase for acid (b)pH `= 5 RARR [H^(+) ] = 10 ^(-5) ` ` pH = 11 rArr [H^(+) ] = 10 ^(-3) ` `therefore 100 `times more basic ( c )`pH = 8 rArr [H^(+) ] = 10 ^(-8)` `pH = 11 rArr [H^(+) ] =10 ^(-11) ` `therefore 100 `times more acidic (d)KOH is basic ` 10 ^(-9)` M KOH `rArr pH GT 7`but slightly GREATER
