I've heard that root hair cells in plants secrete acids to help 'solubilise minerals' so that they dissociate and are in ion form... this supposedly allows them to be absorbed.
How so can acids solubilise certain compounds? It must be noted: I am a student and my solubility knowledge is fairly basic. I understand that ionic compounds dissolve in water because of the water molecule and the compound's polarity, but it goes no further than that.
Thank you in advance.
