Jua Jua!!! y necesita colocarse antiparras para pesar un tapón de tubo de ensayo, qué tipo de seguridad usará si tuviera que manipular acido sulfúrico!!!

I sure hope you're not measuring the mass of sulfuric acid in this kind of balance!

No no no,,, not tergiversing comments, its no frecuent to weigth sulfuric or acids,, except when prepare, eg a 1N solurtion, and more, you would use a granatary, then you will normalize that.. So you are answer in the joke form, I hope,, look,, you are "talking" with a chemist not a rookie, . I have two type of these,, one H80 and a Ohaus 101. Older I have a two plates balance too. And finaly,, what kind of risk is to measuring the mass of sulfuric, except the water absorption, that acid is a non fume expeler, like chlorhydric? despite it´s no reasons to weigth acids on it., and I can weigth cinnamic acid, oxalic acid, ftalic acid etc...so?

I mean no offense. I'm not even sure what you're original reply was; I used the google translator. I would recommend a different balance when measuring concentrated sulfuric acid, but perhaps you did not mean that. I'm only a chemistry teacher, not a true chemist like you!

Ok,my dear Sir, but is my sense,that is the majority of times,this videos are not a line of learn, because the information is fragmented by no time disponible (asquible)to show all that. Look, I´m searching a good comunicator for do this, but is a awersome task. I thought about to show some of the aspects of chemist but I conclude that´s is a complex and enormous work,to show in a true form. I´m retired, I´be 71,but I´m working in some development, because I can´t to be a resting man. I think that chemist students no need or no search this information here for a weigtning,,,with a mettler or the like, I think that a complete video of how to weigth with a balance is of about an hour or more of teaching, minimun, because you must explain about what is weigth,for exp. furthermore that´st need a good planing and production and direction,filmation,ligthing etc,etc,etc,it´s an denormous task,,, regards Sir

I'm also retired. This video was a student project for extra credit.
