What Does Titration Mean?

Titration is the method used to find out the normality or concentration value of an acid or a base. Sometimes it is necessary to know the normality of the acids and bases. In a titration lab acid starts in a beaker and is added to with a few drops of sodium hydroxide. This causes the acid to change color. When the color begins to change it tells you the concentration level of the acid.

Each titration will have a curve at some point on a chart. You can make a graph to plot the points at which titration happen with each acid or base. The titration curve is supposed to have an inflection point to it. This is where the curve in the titration will start to change its direction or color which will then connect with the other point. Now that the pH is at the point the basic groups are now open to be found out. The titration curve will now create a shape close to a sigmoid and curves almost like stone steps. The dissociation and the pH can now correspond with the point.

The titration taking affect and changing color.

All of the parts to a titration experiment.

My related topic to titration is acids and bases. It is because acids and bases are commonly used in titration experiments. An acid is a sour taste, for example lemons and vinegar. Acids are in food we eat and in chemistry labs that are not supposed to be ate or drank. Be careful with acids that you don’t know what they’re called. A base can feel slippery and can turn blue when they are mixed with acids. Some bases are egg whites and mineral limes. Some bases can be used in cooking and some may be just for a lab so be careful because some do look a lot alike.

Transition: to change
Acid: sour
Bases: slippery
Titration: to know the normality of an acid or base
Normality: conforming to be normal
