Dispersion relation \(\omega (q)\) a for different values of \(\beta = 0, 0.05, 0.1, 0.2 \) and \(c_{\rm{B,0}} = 0.25\) revealing the strong impact of the dissociation constant on the spinodal decomposition; b for different initial concentration of component B (phosphate ions) \(c_{\rm{B,0}} = 0.1, 0.15, 0.2, 0.4 \) and \(\beta = 0.1 \). Shared parameters: \(D_{\rm{A}}={100}\), \(D_{\rm{B}}={1000}\), \(\alpha =10\) , \(c_{\rm{A,0}} = 0.25\)
