Distinction Level BTEC Applied Science Assignment A - Titration Practical - Making a standard solution. Why is it important to calibrate equipment Making sure that your equipment is calibrated is a crucial step in assuring the accuracy of your data. If you use equipment that read the wrong quantity, they'll be useless. If this step is skipped, it might lead to working with too much or too little of a substance, which can be problematic in some situations. To ensure that our results are as p...

Distinction Level BTEC Applied Science Assignment A - Titration Practical - Making a standard solution. Method on calibrating scales 1. First tare your skills and make sure that it reads 0 2. Then carefully place a standard weight in the middle of the scale 3. Wait for the scale to stop processing the scale 4. Write down your results in a table 5. Assess if your results shown on the scales correspond with the actual weight of the scales My hypotenuses All of the standard weights, I predi...
