Answer questions 1, 2, 4 What is the solubility of Borax in the room temperature

Question

Answer questions 1, 2, 4 What is the solubility of Borax in the room temperature solution? What is the solubility of Borax in the ice bath solution? In which solution is Borax more soluble? The enthalpy change (Delta H degree) for borax dissolution can be determined using Equation 6 below, where Ksp, is the solubility product constant at room temperature in Kelvin (T_1) and Ksp_2 is the solubility product constant at ice bath temperature in Kelvin (T_2). ln (Ksp_1/Ksp_2) = Delta H/R (1/T_2 - 1/T_1) From your experimental results, calculate the enthalpy change in kJ/mol. R = 8.314 J/mol. Delta H degree
