An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

pH determination and acid–base titrations are essential experiments performed by high school and university undergraduate students alike throughout their chemistry education. While these experiments ...

In most chemistry curriculum, students attend practical trainings in physical laboratories to reinforce their theoretical knowledge. However, the availability of these facilities can be limited or ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...

There’s a spill in a laboratory. This is obviously a huge safety concern, particularly if we don’t know what it is. Handily, if it is an acid or a base there are techniques which can be used to see ...

Purpose: In this paper, the estimation acid and base from locally available materials were studied. The main purpose of this research was to study to implement the use of locally available materials ...

Each chemical reaction involves an enthalpy change that leads to a change in temperature. The amount of substance converted during the reaction determines the increase (i.e. exothermic reaction) or ...
