Hydronium

Freezing point is the temperature for a particular compound where the liquid freezes to form a solid (Chemistry Dictionary). If salt is added to water, it freezes at lower temperatures. If there are fewer water molecules, then freezing occurs at a slower rate (Salt and the Freezing Point of Water). Pure water freezes at 0º Celsius, but water that is combined with salt will freeze at a temperature less than 0º Celsius (Oleson, Andrew and Daly, Terik). A solvent is something in which other things…

The purpose of this experiment is to determine the pH of known substances by use of a pH color indicator of red cabbage and the use of a pH meter. As well as, to observe the pH changes in a substance by adding in more basic of acidic to buffered solutions and unbuffered solutions. This experiment will also will show how to calculate H3O+, OH- and pH by use of known values. In order to do this lab, there are a few key components one needs to know and understand first. A solution is a homogeneous…

with a pH of 1? What is the H+ concentration of a solution with a pH of 10? Of these two solutions, which of these solutions is more acidic? What is the difference in acidity between the two solutions? pH is defined as the negative log of the hydronium concentration (often stated as the concentration of hydrogen): pH=-log⁡([〖H_3 O〗^+ ]) or pH=-log⁡([H^+…
