Water, pH and Macromolecules The effectiveness or capacity of a buffer solution can be affected by temperature of buffer components molar concentration of the buffer components both (a) and (b) concentration of the conjugate base to the weak acid temperature of buffer components molar concentration of the buffer components both (a) and (b) concentration of the conjugate base to the weak acid ANSWER DOWNLOAD EXAMIANS APP
Water, pH and Macromolecules A compound that is capable of forming hydrogen bonds with water contains at least some polar covalent bonds should act as a good buffer for acids and bases does not dissolve well in water is probably held together by noncovalent bonds contains at least some polar covalent bonds should act as a good buffer for acids and bases does not dissolve well in water is probably held together by noncovalent bonds ANSWER DOWNLOAD EXAMIANS APP
Water, pH and Macromolecules Polyprotic acids such as H3PO4, can act as acid-base buffers at pH values around any of their pKa's at pH values around neutrality only in combination with polyprotic bases if their concentration is kept low at pH values around any of their pKa's at pH values around neutrality only in combination with polyprotic bases if their concentration is kept low ANSWER DOWNLOAD EXAMIANS APP
