So theres a liter. Its really important to wear safety gloves while youre doing this because this stuff really can burn. Youre going to be amazed at how little one gram is. Very slowly, Im getting it in there. China Y Type Strainers Suppliers Um, once this is dissolved were going to be putting it in this jug. Then Im going to measure out, with my very accurate scale, one gram of the catalyst Im going to use when I make biodiesel.
Thats one very important thing to know. Its quite potent stuff. What were going to do is take this gram of our catalyst and were going to introduce it to our water. Kay weve finished putting our stuff in there. If your chemicals are clumpy in any way, shape, or form, these are nice and clean, then you may need to get new potassium hydroxide or sodium hydroxide. Very carefully Im going to measure China Butterfly Check Valves Manufacturers out a gram of KOH.
One thing that is very important is you need to make sure that your chemicals always stay dry. My catalyst of choice is potassium hydroxide, so Im going to balance my scale out, and then Im going to set my scale to one gram. The next thing were going to do is do an actual titration. The first thing were going to do is were going to take and add a liter of distilled water to a container. Kay and weve got a gram.
If they dont, theyll ruin themselves much like hydrogen peroxide; if you leave the lid off it will destroy itself as well. You can use this titration solution for multiple titrations, however, I recommend that every ninety days you get rid of it and put a new titration solution together, and thats because the KOH, the sodium hydroxide, the potassium hydroxide tends to oxidize with time, air, and UV rays, so you just need to make sure that youve got fresh stuff or youre going to get false readings.
Thats because oxygen from the air will react with it and neutralize it. You can put this (the container) away, your funnel away and save it for when you need to remake your titration solution because youre only going to have to do this once. Um, this is probably when you need to be the most cautious though because you are dealing with chemicals.So now were going to do an actual titration. Theres the first part you only do once and thats getting your titration solution ready. Im going to seal this up, and just to make sure its good and mixed in I shake it a little bit. Notice itll fall.
Kay, we know have fully dissolved catalyst in our liquid here, so were going to just pour this right into our jar. This jar, we will use this for our titration solution going forward. Its one of the reasons I like to use potassium hydroxide, is potassium hydroxide will almost dissolve on contact. Theres two parts to doing a titration. So Im going to let this wait for a minute and well stop for a moment and come back when its dissolved. It will take a little bit of time to dissolve here, sodium hydroxide takes forever to dissolve by the way. Then were going to allow this to dissolve
