Pani futle ki notun kono podartho toiri hoy, naki shudhu panir obosthai bodle jay? Pani futey bashpo hoy, thanda hole abar panite fire ashe, tai ekhane pani pan-i thake; eti bhautik poriborton. Kintu ilektrolaisise ghotona alada. Upoyukto poribahi madhyome panir moddhe bidyut probahito korle, bidyut shudhu jol gorom kore na ba soray na; panir joug bhenge jay. Tokhon duti notun gas, haidrogen o oksijen, toiri hoy. Haidrogen o oksijener dhormo panir theke alada, etai notun podartho toirir sposto proman. Orthat shurute chhilo pani, sheshe paoa gel bhinno boishishtyer dui podartho. Ekhanei asal mor: notun podartho toiri howa rashayonik bikriyar prodhan lokkhon. Tai ilektrolaisis mane shudhu bidyuter probhab noy. Bidyut ekhane poriborton-ti ghotate shahajyo kore, ar jouger bhangon ghotiye notun podartho toiri kore. Sutorang proshner uttor, ilektrolaisise shudhu obosthar poriborton hoy na; rashayonik bikriyar maddhome notun podartho toiri hoy.
