Understanding the origins of fast ion transport in solids is important to develop new ionic conductors for batteries and sensors. Nature offers a rich assortment of rather inspiring structures to elucidate these origins. In particular, layer-structured materials are prone to show facile Li+ transport along their inner surfaces. Here, synthetic hectorite-type Li0.5[Mg2.5Li0.5]Si4O10F2, being a ...

If you added 250 cm 3 of water to a solid and then stirred it, the resulting volume is quite often not exactly 250 cm 3. Interactions between the substance you are dissolving and the water molecules can cause the volume of the solution to change. This is why you are using a volumetric flask - because you are making the solution up to a known ...

Feb 10, 2019 · Next, slowly add your 4 mL of stock solution (sulfuric acid). Swirl the flask and then top it up with more distilled water to the 10 mL mark. Caution! As you may have noticed, we added the sulfuric acid to the distilled water in the volumetric flask not the other way around. Why is that? We did this in order to prevent the solution from exploding.
