Ok, i need a help. Knowing that the initial concentration of phosphoric acid
within a pool is 0.3mg. L-¹, and considering the equilibrium constants and the equilibrium expressions placed in the figure, determine the concentration of all specific species in the solution.

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

In which of these cases are the two wave points considered to be in phase with each other?
