Molar solubility concepts and principles. Assume a temperature of 298 K. "MOM" or milk of magnesia, magnesium hydroxide, is a common antacid tablet used because it is a weak base and slowly dissolves as it neutralizes stomach acid. Print the neutralization reaction with appropriate use of Ea, change in enthalpy, etc. What chemical group is magnesium in and then consider its usual charge: That is, magnesium hydroxide is not a 1:1 chemical compound. MOM acid / base soothing equation: a. Calculate the molar solubility (often defined by s) of magnesium hydroxide in pure water. Ksp = 5.61 x 10?12. Do not forget to print a balanced dissociation equation. b. (7 points) Calculate the molar solubility of magnesium hydroxide in 0.050 molar calcium hydroxide. Is this a common ion problem? If true, then what is the common ion based on the extent or degree of dissociation of calcium hydroxide. c. Does the solubility of "MOM" increase or decrease or remain constant when ingested? Explain by stating one or more chemical equations.
