Calculate the pH of each solution. A solution containing 0.0215 M maleic acid and 0.0290 M disodium maleate. The a values for maleic acid are 1.20×10−2 (a1) and 5.37×10−7 (a2).
pH=

A solution containing 0.0300 M succinic acid and 0.017 M potassium hydrogen succinate. The a values for succinic acid are 6.21×10−5 (a1) and 2.31×10−6 (a2).
pH=

Thank you for the help! I know i have to use the Ka values and the HH equation but it always comes out wrong for me :/

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
