Answer is: pH value of weak is 3.35.
Chemical reaction (dissociation): HA(aq) → H⁺(aq) + A⁻(aq).
c(HA) = 0.0055 M.
α = 8.2% ÷ 100% = 0.082.
[H⁺] = c(HA) · α.
[H⁺] = 0.0055 M · 0.082.
[H⁺] = 0.000451 M.
pH = -log[H⁺].
pH = -log(0.000451 M).
pH = 3.35.
pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous solution.</span>

Which type of carbon fixation stores carbon dioxide in acid form?. a. C3. b. C4. c. CAM. d. all of the above
Tcecarenko [31]

Answer is: c) CAM.

CAM (crassulacean acid metabolism) is a carbon fixation pathway.

In plants with CAM carbon fixation, carbon dioxide is stored as the malic acid malate in vacuoles at night.

During the daytime, the malic acid is transported to chloroplasts where it is converted back to carbon dioxide, which is then used during photosynthesis.

Malic acid is an organic dicarboxylic acid with the molecular formula C₄H₆O₅.
