Practicals Chemistry AQA A-level Rated A+ Required Practical 1 - titration and making a standard solution Making a standard solution 1. weigh the required mass of solid using a sample bottle on a 2 dp balance. 2. transfer the solid into a beaker using distilled water to wash it out- preventing any solid remaining in the sample bottle. 3. reweigh the sample bottle and work out the difference. 4. Add 100cm3 of distilled water to the beaker to dissolve the solid (small volume of water) using a...

She returns to her old neighborhood and purchases heroin and injects herself with the 'usual' amount of drug she had habitually taken. She then collapses and becomes unconscious with shallow respirations within 1 minute of use. The most likely cause is a(n): Reaction to a contaminant in the heroin Increased drug purity Loss ...

Test for hydrogen Squeaky pop Test for a Carbonate anion (CO32-) React with an acid to release carbon dioxide gas. Effervescence is observed and the production of carbon dioxide can be confirmed using limewater. ALTERNATIVLEY: A solution of a carbonate will also be alkaline, which can be shown using universal indicator or a pH probe. Ionic equation when testing for a carbonate anion: 2H+(aq) + CO32−(aq) → H2O(l) + CO2(g) Silver compounds are all ______________ except for ________...

Edexcel iGCSE Chemistry, question and answer with rated solution Experiment for Diffusion? 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? 1) Put a coloured substance in a solvent e.g food colouring in water. 2) Over the time, the colour le...

silicates - minerals that contain silicon and oxygen and usually one or more other elements, are one of the largest groups of minerals oxides - compounds that have oxygen as their anion, t ut they exclude those with oxygen complexes such as carbonate, suphate, and silicate. have O2 as their anion, Ways rocks may form - Igneous: forms from magma that has either cooled slowly under ground or cooled quickly at the surface after a volcanic eruption Sedimentary rocks: formed when weathered frag...
