IB Biology Lab – Vitamin C content of food Aim: To compare the vitamin C content of different fruits using the decolourisation of DCPIP from blue to clear as the indicator. • You first need to estimate the volume of a known concentration of vitamin C solution required to decolourise 2 cm3 of DCPIP solution. • Then you need to determine the volume of fruit juice that decolourises 2 cm3 of DCPIP solution. This gives an estimate of the concentration of vitamin C in fruit juice. • This

As patients get injured or as they age; there is a growing need to have assistance with releasing urine from the bladder. A major problem with urinary catheters is that whilst they drain the bladder‚ they

Investigating the vitamin C content of fruits and fruit juice Aim: In this investigation‚ I aim to measure and compare whether there is a higher content of vitamin C in a fruit or a juice by measuring the volume of the sample required to decolourise a solution of dichlorophenolindophenol (DCPIP). Introduction: For this experiment‚ I aim to investigate and compare the content of vitamin C in the fruit against the fruit juice. The theory of this method is a titration with dichlorophenolindophenol

Cytochrome-C Comparison Brief Description: The molecular clock refers to mutations in DNA nucleotide sequence of genes occurring at a constant rate over time. The greater the difference in nucleotide sequence between two individuals of different species‚ the greater the amount of time has passed since they diverged from a common ancestor. The molecular clock helps to provide evidence to support conclusions previously based on comparative morphology and fossil records. Hypothesis: One hypothesis
