Water, pH and Macromolecules The effectiveness or capacity of a buffer solution can be affected by both (a) and (b) molar concentration of the buffer components concentration of the conjugate base to the weak acid temperature of buffer components both (a) and (b) molar concentration of the buffer components concentration of the conjugate base to the weak acid temperature of buffer components ANSWER DOWNLOAD EXAMIANS APP
Water, pH and Macromolecules The main difference between an acid and a base is that acids are polar molecules and bases are not bases are polar molecules and acids are not bases donate hydrogen ions in water while acids accept hydrogen ions acids donate hydrogen ions in water while bases accept hydrogen ions acids are polar molecules and bases are not bases are polar molecules and acids are not bases donate hydrogen ions in water while acids accept hydrogen ions acids donate hydrogen ions in water while bases accept hydrogen ions ANSWER DOWNLOAD EXAMIANS APP
