Acid-Base Titration - correct answer1. Fill a burette 2. Use a pipette to transfer 25cm³ of the other solution into the conical flask 3. Add 2-3 drops of indicator 4. Start adding from the burette, swirling constantly, until the indicator changes colour. Record how much solution was added (rough titre) 5. Repeat to get concordant results and calcul

Acid-Base Titration - correct answer1. Fill a burette 2. Use a pipette to transfer 25cm³ of the other solution into the conical flask 3. Add 2-3 drops of indicator 4. Start adding from the burette, swirling constantly, until the indicator changes colour. Record how much solution was added (rough titre) 5. Repeat to get concordant results and calculate a mean titre Anti-Bumping Granules - correct answerSmall, rough pieces of silica that are added to the mixture before reflux. They provide...

A large difference between experimental and calculated lattice enthalpy values are due to... - relatively large degrees of covalent bonding. positive ions can be said to polarise negative ions, if they cause distortion of the charge cloud. They can pull electrons to one side of the ion. As temperature rises what happens to the rate constant? - As temperature rises, the rate constant gets larger, so the rate is faster As the activation energy rises what happens to the rate constant? - As...

Carry out simple test-tube reactions to identify anions. 7 - halide ions- add small volume of nitric acid to solution followed by silver nitrate solution. different coloured ppt shows different halide ions, add excess dilute ammonia solution followed by conc ammonia solution to confirm halide ions. group 7 solid salts- add conc sulphuric acid to potassium halide. record observations, KCl- white misty fumes, KBr- orange fumes, KI- purple fumes and purple/black solid. test gas with damp blue litm...

aqa a level question and answer

Amino Acid - correct answerOnly different and specific in the R group. The R group represents a side chain from the central 'alpha' carbon and can be anything from a simple hydrogen atom to a more complex ring structure. The R group defines the amino acid. Glycine is the only amino acid that does not contain carbon. 20 amino acids make up all living things. Amylopectin (75%) - correct answer- Long, branched chain of alpha glucose -Side branches allow the enzymes to break down the mol...
