Question
5 Wnte a reaction for the neutralization that would occur if you added a small amount of NAOH to the buffer solution desribed in question 3. Ca(OH)2 pre-lab At 1) What are you using as an indicator in this lab? What color indicates the titration has reached completion? 2) The molar solubility of Mg(OH)2 is 1.51 x 10 M. What volume Of 0.002 M HCI would be required to titrate 100.0 mL of saturated Mg(OH)2? 3) At the end point of the titration, what would happen if you added a few drops of NaOH? Why? Borax Pre-lab A 1) As the temperature of the solution increases, does the Ksp increase or decrease? 2) You will be using bromocresol green as the indicator for the titrations, What color will indicate the titration is complete? 3) After titrating at several temperatures, you will make a plot in Excel with vour data, What will go on the y axis? What will go on thex axis? 4) If the equation for the line is y = 300x + 25, solve for the change in Enthalpy, change in Entropy, and change in Gibbs energy at 65 °C and include all units.
