percentages of ferrous sulfate heptahydrate in aqueous solution

Is magnesium sulfate basic, neutral or ... Stack Exchange
"The pH of an aqueous magnesium sulfate solution is related to the molarity of the MgSO4. Typically, the pH is between and due to magnesium's affinity for hydroxide ion (OH). As the sulfate goes into solution, hydroxide anions associate with the magnesium, increasing the relative ratio of H+ to OH.
