How to

Calculate the Concentration of a Solution

In chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. The standard formula is C = m/V, where C is the concentration, m...

Calculate the Enthalpy of a Chemical Reaction

Use Hess’s law to quickly find the enthalpies of reactionsDuring any chemical reaction, heat can be either taken in from the environment or released out into it. The heat exchange between a chemical reaction and its en...

How to

Read pH Strips

If you’re interested in testing the alkalinity or acidity of a liquid, you can use pH strips to help you determine the pH level. If you’ve never used a pH strip, though, it might look like just a plain strip of paper...

How to

Raise the pH of Water

Water typically has a neutral pH around 7, but added minerals and chemicals can cause it to drop into acidic levels. Overly acidic water can change your body’s pH levels when ingested, harm fish in an aquarium, or caus...

How to

Calculate Bond Order in Chemistry

On the atomic level, bond order is the number of bonded electron pairs between two atoms. In diatomic nitrogen (N≡N), for instance, the bond order is 3 because there are 3 chemical bonds linking the two nitrogen atoms....

How to

Adjust Water pH

pH measures the amount of acidity or base in a liquid. If you need to adjust the pH level of your water—whether for a science experiment, gardening, drinking water, a fish tank, or any other need—begin by measuring t...

How to

Calculate pH

You can calculate the pH of a chemical solution, or how acidic or basic it is, using the pH formula: pH = -log10. Anything less than 7 is acidic, and anything greater than 7 is basic. Check out the steps below to learn h...

How to

Dilute an Acid

Purchasing the most dilute acid that will meet you needs is recommended for safety and ease of use, but sometimes you will need to dilute it further at home. Do not skimp on safety equipment, since concentrated acids can...

How to

Test pH

The pH level measures how acidic or alkaline a material is. Distilled water is neutral and measures 7.0 on the pH scale. Materials from 1-6 are acidic and materials from 8-14 are alkaline. If you'd like to find out for y...

How to

Study Muscle Anatomy

There are over 600 muscles in the human body, and memorizing them all can be really tough. However, it will be a lot more manageable if you break the task into chunks. In addition, learning the root words that make up th...

How to

Prove That Light Travels in a Straight Path

Get Good Grades in Chemistry

Chemistry, like other math-heavy fields in the sciences, is a subject which requires hard work and effort to master. Chemistry entails equations, formulas, and diagrams; some of these may have to be memorized, while othe...

How to

Distinguish Between Acids and Bases

In chemistry, the easiest way to distinguish acids and bases is to look at the substance's pH level—acids have a pH of less than 7 while bases have a pH greater than 7. But what if you don't happen to have any litmus p...

How to

Pass Organic Chemistry

Organic Chemistry has a nasty reputation — it's not uncommon for students to hear horror stories about the class's difficulty before they have a chance to take it themselves. While the class can be a challenging on...
