Allow to stand until the next laboratory period.

Just like the silver nitrate-hydrochloric acid reaction, we only had to wait one day to achieve complete precipitation. God is good, and His grace is infinite, so I am now a licensed pharmacist, and our batch was able to bring glory to our alma mater.

And please allow me to give a simple speech of gratitude. To our families and loved ones. To the people who gave us what we needed to have. To the people who taught us what we needed to know. To the people who believed that we can make it. To the people who challenged our capabilities. To the people who shared their time and knowledge without asking for anything in return. To the people who were there, every step of the way. Thank you for the prayers, for the encouragement, for the help. We wouldn't have made it without you. With your help, and because of God's amazing love, I am now Jazel Elaine E. Ignacio, R. Ph.

Silver nitrate - hydrochloric acid reaction - a step in the standardization of silver nitrate solution that yields white precipitates of silver chloride which are insoluble in water but soluble in nitric acid. The whole process is performed in the absence of light to prevent oxidation of silver molecules.
