SOLVED: As the Ca(OH)2 solution is added to the HCl, What is happening at the molecular level? Write the equation for the chemical reaction that is taking place. As the addition of the calcium hydroxide approaches, a pinkish color will appear but will instantly disappear. Why does this occur? Continue to add calcium hydroxide dropwise, until a permanent light pink color is obtained, which should last for  20 seconds with swirling the flask. Why is it necessary to swirl for 20 seconds?
