Magnesium hydroxide is only very slightly soluble in water. The reaction by which it goes into solution is: Mg(O H)2(s) = Mg2*(a q) + 2 O H minus (a q) What will happen if OH minus is added to the solution and why? O Solid remains. OH minus concentration increases. Reaction moves to the right. Solid dissolves. O H minus concentration decreases. Reaction moves to the right. O Solid remains. O H minus concentration increases.

States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
