High School Lab Equipment
Are you a teacher? If you are, you will need quality high school lab equipment with which to equip your high school chemistry lab. This will entail obtaining high quality glassware, personal protective equipment and the right chemistry textbooks for the job. It is important that you have enough sets of high school lab equipment to equip each lab bench with the necessary tools to complete each and every assignment completely, correctly and safely.
What would a well equipped high school chemistry lab have so as to be equipped properly? It would certainly have the following items: Professional Chemistry Lab Sets. A professional chemistry lab set would include a variety of items such as: Electronic Digital Balances for weighing our materials used in reactions, Test Tubes for combining small amounts of reactants for easily observable lessons, Support Stands With Cast Iron Bases for setting up glassware used in experiments, Cast Iron Support Rings to assist in this function, Buret Clamps also to assist in this process.
Additionally, you would need Wire Gauze and Bunsen Burners to setup up for boiling and effecting reactions and digestions, Porcelain Crucibles With Lids for oxidation reactions and evaporation of hydrates and solvents, Glass Graduated Cylinders for measuring liquids, Shaped Separatory Funnel With Glass Stopper for extractions, Volumetric Flasks for solution preparation, Graduated Glass Beakers to measure and as reaction vessels, Glss Laboratory Thermometers to track liquid temperatures, Poly Wash Bottles to keep everything rinsed and clean, Assorted Diameter Rubber Lab Tubing for pulling a vacuum.
Furthermore, you will need Glass Tubing for fashioning custom glass tubing setups, Dropping Pipets (medicine droppers) for measuring out small amounts of liquids, Glass Stirring Rods for facilitating mixing, Test Tube Clamps, Crucible Tongs and Beaker Tongs to hold test tubes, crucibles and beakers, Stainless Steel Forceps to handle hot and reactive materials, a Spatula that is Stainless Steel for measuring reactants, a Clay Pipe Triangle to hold a crucible, Weighing Canoes for measuring on the mass balance as well as Rubber Stoppers.
Most important is PPE. PPE stands for Personal Protective Equipment. PPE is essential to a complete set of high school lab equipment. When working in a lab, protection for you eyes, skin and respiratory system is absolutely necessary. Safety goggles would fit snuggly round your eyes so as to help protect your eyes from spill and splashes that result from spills in the lab. Additionally, a lab coat would help to protect your skin and your clothes from materials that can splash and burn or irritate your skin and eat holes in your clothes after they are washed. Additionally, chemical resistant gloves are useful in helping to prevent exposure with respect to your hands. Safety should be top priority in any lab. High School Chemistry lab Textbooks.
If you are going to equip your high school with lab equipment, you will need well outlined chemistry lab textbooks to provide you with experiments that you can perform. Chemistry lab textbooks that are well written with step-by-step instructions included as well as strong emphasis on safety.

Chemistry question, help please?
A student was given a flask that contained either C7H15COOH(s) or C9H19COOH(s). (Both substances are monoprotic weak acids).
The following materials were available to help idenitfy compound:
- centigram or pan balance
- erienmeyer flask or 100 mL beaker
- buret and clamp
- 0.10 mol/L KOH(aq)
- phenophatelin indicator
- distilled water
1. WRite an experimental design outlining a procedure that could be used to spcifically idenitfy the substance as either C7H15COOH(s) or C9H19COOH(s).
2.Explain how this procedure would indenfity the substance.

Thanks 4 your help.
Think about it. A titration against standard base will tell you the moles of acid in a sample, x the number of available H+ per formula unit of acid (1 in each case)
So you can work out the number of moles in a sample that you make up. But since you made it up, you know the number of grams. From number of grams, and number of moles, you can work out the molar mass.
Take it from there.
