in some cases, there may be a mixture of two or more acids. When this happens, the stronger acid will dissociate completely, so you should be able to calculate how much H,0 is in solution as a result. Writing out the equation for the dissociation often helps The weak acid will attempt to dissociate and is governed by the equilibrium (K,). You should write out the equation for the weak acid Now-write in the values for the concentrations that you'll...

Would someone be able to explain the difference between salts and normal weak/strong acids/bases? I'm trying to learn solubility and acid base equilibrium and I'm not sure what the 'salt' means and how this relates to if something is more or less soluble in an acid or a base. thank you!
