What is the maximum size gas syringe could I use for an experiment?
• I am planning my A2 individual investigation and have decided to investigate silver nitrate titrations to determine the amount of chloride ions present in my solution. If I change the concentration of my silver nitrate and sodium chloride solutions do I have to change the concentration of potassium chromate (indicator) as well? Also I am going to adapt this technique to work out the salt content of certain foods. I found out that I need to use conductivity as the end point but I dont understand how I go about finding this method out as there is only one website I have found that mentions it. Please can you help? • I am doing an investigation on the analysis of wine. I have looked at an article from Chemistry Review (Jan 98) by Derek Denby and in it he talks about how to find out what the alcohol content of wine is. One method is to oxidise ethanol using an excess of potassium dichromate and then doing a back titration using ammonium iron(II) sulphate. I really need an indicator for t
