Hello everyone. Today we're going to be going over the basic procedure of how to do a proper titration. Let's get started. The first thing you're going to want to do is to rinse your beret. Simply take your beret, open the stock caulk, and pour in some hot water until it's about a third full. Let it prop smelly half of that water drain. Close the stock caulk and pour the rest into the sink by rotating the beret. Thus coating the inside. Repeat this procedure until you've done it three times with hot water, three times with the iron ice water, and three times with your solution. This demonstrates a proper setup for your titration. You have your beret filled with your solution attached firmly to the ring stand with the clamp as shown here. Make sure your clamp is secured tightly. Underneath the beret you have your waste beaker and your prepared solutions. The stock caulk is the white plastic part as seen on the beret. The stock caulk is closed when it is perpendicular with the beret. When you're ready to begin your titration, simply remove the waste beaker underneath the beret and place your Erlemire flask with your prepared solution underneath the beret. Once you've done this, make sure that you take your initial rating of the beret which in this case is 4.94ml. You are then ready to begin your titration. Slowly turn the stock caulk until your solution begins to appear out of the beret. With one hand on the Erlemire flask and the other on the stock caulk, gently swirl the solution. You do not want solution pouring out of the beret simply a constant drip as you do not want to overshoot your endpoint. When you begin to see a change in color, as you see here, turn the stock caulk to closed and put the solution down. Watch your solution, if it reverts back to its original color, you simply need to add a half a drop or drop more and it should reach its endpoint. If it stays that color, as it does here, then you reach the endpoint. You can add a half a drop by simply turning the stock caulk gently until a drop begins to form at the end of the beret but does not fall into the solution. Simply touch the beret to the Erlemire flask and the drop should fall in. When you have reached your endpoint, take the final reading, which in this case is 15.01 milliliters. And there you have it, a basic titration. When you are finished, make sure to dispose all the solutions in the proper containers generally in the fume hood. Wash all your glassware three times with hot water, three times with the ironized water, and return your berets and glassware to the proper place. Making sure that the stock caulk is parallel with the beret to allow it to dry properly. Good luck and have fun!
