Used vinegar and baking soda to make the liquid. Boiled off the water to leave a super saturated salt solution. The salt is normally a solid at room temperature, so when it cools off in the waffle iron, it solidifies. Vinegar contains the acetic acid. Baking soda is sodium bicarbonate. Sodium acetate is the salt formed. There could be some molding potential for this material. I wonder what interesting creations could be made by pouring this liquid into a mold, as is done with concrete? I ...

phone, at low cost, without the need for a computer or Internet access. Telemedicine is best suited for visually-based diagnostics, and thus is ideal for use with cervical cancer screening using visual inspection with application of 4% acetic acid (VIA), a simple, inexpensive alternative to cytology-based screening. It is our goal to use mobile telemedicine to provide accurate diagnosis of precursor lesions, and appropriate triaging and implementation of therapy for women at risk for ...

This is University of Minnesota's second run in the 2009 AICHE Chem-E-Car team national competition in Nashville, TN. The car is powered by generating CO2 by mixing sodium bicarbonate and acetic acid in a pressure vessel. A ball valve is released , and the pressurized CO2 is used to extend a single stroke piston. A series of strings and pulleys attached to the piston drives the car forward. Friction slows the car to a stop. On this run, the car stopped approximately 4 feet past the line ( ...

introducing the water and then closing the system. Ammonia gas dissolves into the water, reducing the pressure in the system of flasks. Atmospheric pressure pushes the acetic acid solution into the system. Ammonia gas dissolves into the solution, neutralizing the acid and turning the solution basic. As more acetic acid solution is introduced into the system, the colors continue to change. At equilibrium, the pH and therefore the color is dependent on the relative amount of ammonia ...

: Mg2+(aq) + 2 e- → Mg(s) E° = -2.356V by using tincture of iodine, copper wire, and nitric acid from fertilizer, you can obtain copper ions and iodine ions which will form copper iodide. this will then be oxidized by the magnesium and enter the solution in it's half cell. the electrons will travel to the other half cell and cause the magnesium ions (obtained by reacting magnesium with acetic acid) to soldiify on the magnesium cathode causing a difference in potential ΔE = 0.86-2.356= ...

A fanta bottle gets smashed to bits by vinegar and bicarb of soda. by no means my most impressive work on every level, but hey. the bottle is lost in the vid, but is found weeks later on the other side of my house, which is 3 storeys high and 30 metres away from where we were standing. sorry for the innuendo. the chemistry: acetic acid(vinegar)+sodium bicarbonate(bicarb) goes to sodium acetate(hot ice)+carbon dioxide

beverage, whether it is made from apples, grapes, dates, rice or plain white sugar, once exposed to air, will turn naturally to vinegar. It is the ever-present bacteria in the air that converts the alcohol in cider, wine, and beer, into acetic acid, which gives vinegar its characteristic sharp sour taste. So it is safe to say that man has been exposed to vinegar since before recorded vinegar history. Recorded vinegar history starts around 5000 BC, when the Babylonians were using the fruit ...
