Explain what a high Ka value of an acid represents and what a low Ka value represents. State and explain the difference between the endpoint and the equivalence point in a titration
What concentration of Fe^3+ is needed to maintain the phosphate concentration below the limit of 1 mg P/L? Any help on how to do or even start the problem would be great.
The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport chain. The energy from the electron transport chain is used for oxidative phosphorylation.
