Concept explainers

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

1. Enter the data from the table into a spreadsheet program. Use the program to plot the results, with pH on the
vertical axis and volume of base added on the horizontal axis.
**TIPS:
• If using excel, you want to create a scatter plot with smooth lines and markers. DO NOT create a line graph.
• If using google sheets, you can create a smooth line chart.
• Make the plotted points large enough so that they are clearly visible.
• Make sure you can see detail on your grid for accurate interpretation. For major gridlines, count by 1. Show minor gridlines.
Include labels for each axis.
• Provide a suitable and descriptive title.
• A google search will help you with this if you are not familiar with using a spreadsheet to create a graph or how to properly
format. Or you can ask your teacher.
2. Print your graph or export it to a suitable computer program that you can draw on. It should take up the whole
page.
3. On your graph:
a. outline and shade the buffer region.
b. identify the pH range of an indicator suitable for this titration.
c. name two indicators that would have endpoints suitable for this titration.
