This may seem obvious, but people often disregard safety protocols for one reason or another, putting themselves and those around them in danger. The best thing you can do is to make sure you follow all safety protocols at all times.
Safety goggles are required wear in all chemistry labs. Not wearing them puts you in danger of eye irritation and possibly blindness in the case of an accident.
A small droplet of acid could splash out of the container at any time. Better safe than permanently blinded! Latex gloves should be used when there is a possibility of corrosive chemicals spilling onto your hands.
A lab apron or coat can also prevent injury in case of spills or splashes. Never wear open-toed shoes or sandals in a lab. Beakers A beaker is a common container in most labs. It is used for mixing, stirring, and heating chemicals.
Most beakers have spouts on their rims to aid in pouring. They also commonly have lips around their rims and markings to measure the volume they contain, although they are not a precise way to measure liquids. Beakers come in a wide range of sizes.
Because of the lip that runs around the rim, a lid for a beaker does not exist. However, a watch glass discussed below can be used to cover the opening to prevent contamination or splashing. Erlenmeyer flasks, AKA conical flasks Also known as a conical flask, the Erlenmeyer flask was named after its inventor in It has a narrow neck and expands toward its base.
This allows easy mixing and swirling of the flask without too much risk of spilling. The narrow opening also allows for the use of a rubber or glass stopper. It can easily be clamped to a ring stand discussed below as well as heated or shaken mechanically. Once again, the marks on the side are meant primarily for estimation rather than precision.
An important safety tip here is to never heat this flask while it is capped. This could cause a pressure build-up that could result in explosion. Florence flasks, AKA boiling flasks Also known as a boiling flask, the Florence flask has a round bottom and a long neck. It is used to hold liquids and can be easily swirled and heated.
It can also easily be capped by rubber or glass stoppers. Once again, safety dictates that this flask never be heated when capped. Pressure build-up and explosions can and do occur. Test tubes being lifted with tongs from a rack A test tube is a glass tube with one end open and the other end closed.
The closed end is rounded. Test tubes are used to hold small samples.Science Fair Resource Guide - IPL Kidspace, the Internet Public Library If you're looking for help, this site will guide you to a variety of web site resources, leading you through the necessary steps to successfully complete an experiment.
Chemistry (the etymology of the word has been much disputed) is the science of matter and the changes it undergoes. The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned with the composition, behavior (or reaction), structure, and properties of matter, as well as the changes it.

An experienced chemistry professor used to say that it took about one explosion per week to maintain college students' attention in chemistry lectures. 3c – I imagine that once the net ionic equation has been written, simply pointing out that when a weak acid and its conjugate (as shown in the equation) are present, the solution is a buffer, would be sufficient without discussing limiting factors.
