How to Study the Basics of Biochemistry
Biochemistry joins the study of biology with the study of chemistry to explore the metabolic pathways at the cellular level in organisms. In addition to its application to the study of metabolic pathways in plants and microorganisms, biochemistry is an experimental science that relies heavily on the availability of specific instrumentation unique to this discipline. It is a broad topic,

How to Electroplate Household Metals
Electroplating is a process used to coat one metal with that of a separate metal. There are many objects in our everyday lives that have been plated with other metals: gold-plated jewelry, nickel and copper plated coins, etc. The process involves passing an electric current through a solution of electrolytes that allows for the transfer of metal ions from the donor metal to the

How to Get Started in Chemistry
Learning chemistry will help you understand the different forms and properties of matter. Atoms are the small bits of matter that can be added to each other to build anything from water molecules to skyscrapers. The first steps of understanding the complexities of chemistry are to know the elements on the periodic table, understand atoms, and consider why some atoms bond together. This

How to Find the Number of Neutrons in an Atom
Although all atoms of the same element contain the same number of protons, their number of neutrons can vary. Knowing how many neutrons are in a particular atom can help you determine if it's a regular atom of that element or an isotope, which will have either extra or fewer neutrons. Determining the number of neutrons in an atom is fairly simple and doesn’t even require any

How to Prepare a Sorensen's Phosphate Buffer
Buffers are an important part of most laboratory experiments, as they help keep mixtures between a 5.0 and 8.2 pH level. A Sorensen’s phosphate buffer is a non-toxic option for your projects and doesn’t contain any harmful substances, unlike a cacodylate buffer. This type of buffer isn’t difficult to make, though you do need a background in chemistry and some basic laboratory supplies

How to Freeze Water Instantly
Did you know that you can cool water below its freezing point at 32 °F (0 °C) without it becoming solid? This method of instant freezing is called “supercooling.” You can use salt, ice, and water to supercool water bottles in an instant. Supercooled water will remain a liquid until something, like a tapping motion, instantly kickstarts the freezing process.

How to Study Organic Chemistry Effectively
Organic chemistry consists of the study of organic molecules, including their formations, reactions, mechanisms of reactions, product formation, and uses. Most of the compounds studied in organic chemistry contain at least one carbon-hydrogen bond. While organic chemistry can be very difficult, you can make it easier with some basic strategies such as knowing the types of reactions and

How to Measure Organic Matter in Water
Measuring organic matter, or the remnants of organic compounds in the water, can help you track the health of your waterbody and the organisms living within it. If you have access to lab equipment, you can measure the total biodegradable dissolved organic carbon (BDOC) or the amount of chemical oxygen demand (COD) in your water. If you don’t have access to lab equipment, consider

How to Study the Chemical Properties of Transition Metals
Transition metals are the elements on the periodic table that exist between groups 3 through 12. They are metallic elements that have special properties due to the incomplete filling of their outer electron shell. They are generally characterized by their ability to readily form complexes, their use as a catalyst, and the vibrant colors that they form.

How to Get Potassium Nitrate
Potassium nitrate, also known as saltpeter, has many uses. It's the main ingredient in black powder, which was what was used to fire weapons up to the late 1800s. It's also used in fireworks, as a fertilizer, and as a supplement. How you go about getting potassium nitrate is going to depend on what you need it for, whether it's for use as a supplement or as part of a DIY project such as
