Why stopper naoh

ChemBuddy chemical calculators - stoichiometry, pH, concentration, buffer preparation, titrations. Thanks, Borek. A slight silicon contamination wouldn't be detrimental; I'm only worried about the bottle. Laboratory glassware is expensive around here. Anyway, i have no problem with that; I'll just store it in a plastic bottle, and everything will be fine. But I'd like to know what exactly happens, just for the sake of my curiosity.

I'm trying to understand what reactions take place, and why. Think about SiO 2 as acid anhydride - it reacts with base just like CO 2 does. Sure, it is not as eager to do so, but basic idea is the same. The essential information was the solution's concentration. An 1M solution don't give a lot of problems. This is because it contains lactic acid. How acidic is Coke? Its pH is reported to be 2.

As a fizzy drink, it contains plenty of dissolved carbon dioxide, but this makes very little contribution to the acidity. A: Ripe bananas have a pH of about 5, making them a mildly acidic food.

That does not mean that bananas cause heartburn or reflux, however. Skip to content Natural sciences. Why is NaOH stored in rubber stoppered bottles? Table of Contents. Anyone, please share your view. I never spoke about a chemical reaction , just wrote that the Na 2 CO 3 from the reaction of NaOH and CO 2 could combine with the Na 2 CO 3 component of the glass into big crystals, welding the glass stopper and the glass flask together.
