I am doing an investigation on wine acidity. Is there a formula to calculate the number of moles of HO- required for each 100 ml of wine?
Igloo writes
No, there isn’t. It all depends on the acidity of the wine in the first place, and you can only find out about this by experimentation.
Once you have carried a titration, you should carry out a straightforward calculation based on the titration reading, the concentration of the alkali and the equation for the reaction between H+ ions and OH- ions.
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
For further guidance see our tutorial on Risk Assessment.
