Document Summary
The polarity of water will cause the polar solute to dissociate (break down). Nonpolar solutes will not be affected by the polarity of water. Mg has a +2 charge and so4 has a -2 charge. This means that there is one mg for every so4. So +2 and -2 will be in this solution. The acid is a diprotic acid (h2a), meaning that it has two h+ ions in the formula to donate to a base. The reaction is h2a(aq) + 2 naoh(aq) 2 h2o(l) + na2a(aq), where a2 is what is left over from the acid formula when the two protons (h+ ions) are reacted. For the hcl reaction, the base has the ability to accept two protons. The most common examples are ca(oh)2, sr(oh)2, and ba(oh)2. A possible reaction would be 2 hcl(aq) + ca(oh)2(aq) 2 h2o(l) + cacl2(aq).
