Chii chinonzi pH?
PH chiyero chekuita kwehydrogen ion mumushonga.Mvura yakachena ine chiyero chakaenzana cheyakanaka hydrogen ions (H +) uye
negativehydroxide ions (OH -) ine pH isina kwayakarerekera.
● Mishonga ine maion ehydrogen yakakwira (H +) pane mvura yakachena ine acid uye ine pH isingasviki 7.
● Mishonga ine hydroxide ion yakakwira (OH -) pane mvura ndeye basic (alkaline) uye ine pH inodarika 7.
