100 ml of ph=6 (acidic) is diluted to 1000 ml by H2o.The pH will increaae by A) 9 unit B) 0.7unit C) 1unit Sir ans is given 0.7 unit, how??

Hi,

FInd out the concentration of H+ ions before and find the number of moles of the same using 100 ml volume. The moles ions would be constant after too, so get the concentration using new volume and find new PH
