CHEMISTRY Electrolysis Voltameters A voltameter is an instrument for measuring the quantity of electricity (i.e. the amount of electric charge). This is done by measuring the amount of element deposited or released at the cathode. In schools, they are typically used to demonstrate the composition of water being two parts hydrogen to one part oxygen. Student Gas Voltameter Hoffman Voltameter For student experiments. Embedded platinum electrodes are connected via Comprises three parallel tubes, joined at the bottom with a horizontal tube. 4mm sockets. Two miniature test tubes are included for gas collection.

A cheaper alternative is to use nichrome wire, which Boron Green / bright green works well but tends to give a trace of orange colour in a flame. Caesium Blue / violet Calcium Orange-red / brick red It is more effective to use a flame test wire with a loop at the end, Blue-green / green or blue as this allows more of the sample being tested to adhere to the Copper (depending on which ion) wire. Blue Indium Yellow-gold Wires should be cleaned first by dipping the end or loop into Iron Grey-white concentrated hydrochloric acid (HCl) and then placing in a hot Lead Red / crimson (blue) Bunsen burner flame. This process should be repeated until Lithium Light green / yellow green no colour comes off the wire in the flame. Concentrated acid works Manganese Lilac / pink / violet best but diluted HCl can be used instead, although less effectively, Potassium Red / red-violet if safety issues are a concern – the flame colours may not be so Rubidium Orange / orange-yellow intense. Sodium Red Strontium Green Then the end of the wire or loop should be moistened again in the Thallium Blue-green acid, dipped into the sample being tested (so that some sticks) and Zinc placed back into the Bunsen flame. The table lists typical flame test colours for various metal compounds (salts).

If using the bottled gases to fill rubber or latex balloons, due to the surprisingly large volume of a balloon (e.g. a 9\"/23cm spherical balloon would have a volume of approx. 6.3 litres) and also to the pressure the balloon walls exert on the gas, the number of balloons which can be filled will be considerably fewer than expected – probably only 3 or 4 from a 34 litre cylinder (depending on the size of balloon) and perhaps only 1 from a 14 litre bottle.  202 …inspiring tomorrow’s scientists through practical science.

Packed in plastic box with instructions. •Advantages: More effective understanding of formulae • Enhanced motivation • Use of OHP for demonstrations. Covalent jigsaw:- In the covalent jigsaw, atoms are represented by coloured disks with cut-outs corresponding to the positions of atoms in the periodic table. Atoms are joined by clear bonds representing electrons shared between atoms. The covalent jigsaw is available in two boxed sets. Ionic jigsaw:- The ionic jigsaw pieces build on the popular method of using squares and rectangles to aid the determination of ion ratios when constructing formulae. The parts are translucent and can be placed on an OHP for projection. The formulae can be identified by shape, colour and identifying symbols/formulae can be written on them in felt-tip pen.

If the model is held at arm’s length (easier on a firm board) and shaken lightly, the individual ‘atoms’ will vibrate and move independently due to the springs holding them together, but they remain in the same formation within the model, as they do in a solid. Best used for demonstration purposes due to the ease with which the springs can be bent or misplaced. Comprises 9 white ball atoms arranged in a 3 x 3 x 3 lattice, connected by 54 springs.

Saturated KCl solution 4. pH 7 buffer 3. pH 4 buffer 5. Deionised water (last resort to prevent drying out) • Electrodes should never be stored in de-ionised water, unless as a last resort to prevent drying out, testing sample or solvents • Electrode tips should always be rinsed after use • If electrodes need cleaning physically, use a soft tissue and mild detergent or propan-1-ol, (PH25000) • Regularly inspect electrode glass for cracks or chips; if any are present, replace the electrode • It is not unusual for electrodes to have salt deposits present - these will disappear when rinsed • If bulb becomes dry during storage, soak in storage solution, pH 7 or pH€4 buffer for at least an hour prior to use Please Note: most manufacturers of pH electrodes will not guarantee them for more than 3 or 6 months. 218 …inspiring tomorrow’s scientists through practical science.

CHEMISTRY Quickfit/Jointed Glassware Jointed Glassware Sets 14/23 Single Joint Set (‘BU/M Set’) Micro Scale Kit These sets have been designed to cover the essential requirements for the teaching of organic chemistry in schools and colleges, and are difficult to beat The Quickfit® Microscale Chemistry Kit was designed to perform organic for versatility. The sets, made from borosilicate glass, comprise nine items of chemistry experiments, but on a much smaller scale. This reduces your cost glassware housed in a foam insert within a cardboard box (Value Version) or of everything involved - smaller amounts of reagents, lower disposal costs polystyrene insert within a Gratnells tray (Standard Version). and less clamping equipment. Most standard organic chemistry sets may be performed using this set.

The 19/26 19/26 two ranges are compatible with each other. A Socket is a part that has other pieces fitted into it - usually located at the top. A Cone is a part that fits into other pieces (sockets) – usually found at the bottom. A Joint is like a cone but situated on a side arm or side fitting. Explanation of socket/cone/joint sizes, using examples: A socket, size 14/23: This means that the widest Internal Diameter (ID) of the socket– the top of the socket - is 14mm and the length of the socket (the actual ground glass part) is 23mm. A cone or joint, size 24/29: This means that the Outside Diameter (OD) of the widest point of the cone or joint (i.e. the top of the ground glass part) is 24mm & the length of the cone or joint (the actual ground glass part) is 29mm. A cone or joint, size 19/26 will fit into a socket size 19/26, and so on. 222 …inspiring tomorrow’s scientists through practical science.
