Acid etilen diaminotetra acetic (EDTA) ký hiệu H4Y có các pK1 g pK4 lần lượt như sau: 2.0; 2.7; 6.3; 10.3. Tính pH của dung dịch khi Ca = 0.01 M.
Tính nồng độ cân bằng của tất cả các cấu tử với Ca = 0.01M ở pH = 10

Work done = force ×distancebut force = mass ×gravityand gravity = 10m\s force = 2×10 = 20 work done = 20×3 = 60 joules

Fine out your self ponk

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
