BIOL 141 Chapter Notes -Polar 3, Guanine, Glycogen
Document Summary
Ionic bonds: no electrons are shared, positive and negative atoms attract each other, two of the same charges repel each other, hydrogen bonds, weakest bond, when the positive charge on h+ is attracted to a negative charge on another molecule. Chemistry of water: electrolytes ay molecule that becomes at ion when mixed with water, when an ion enters water, the h2o molecules will turn so that their negative sides face the ion, since opposites attract, hydration spheres water shell around an ion or substance dissolved in water, non polar substances (oils) don"t dissolve because they have no charge to attract the water, acid an electrolyte that releases an h+ in water. ph is less than 7, base an electrolyte that binds an h+ in water. ph is more than 7, ph scale measures acids and base in a solution, 0 7 is a acidic (stomach acid, 7 14 is basic (alkaline, 7 is neutral.
