A tomato is indeed a fruit and it's plant toxicity is 12.1.

It lowers the acidity of the tomato
The acidity in the juice removes the dirt.
Sugar is typically added to the tomatoes to neutralize some of the acidity.

No it's not an acid. it will cut the acidity in tomato dishes like tomato sauce or tomato soup. Honey and baking soda will do the same thing. I can't imagine an acid cutting acid.
AcidicWhen cooking with tomato (ex. making a tomato sauce) you can "cut" the acidity by adding a pinch of sugar to the recipe.No, it's slightly acidic.
the acidity in the tomato will help to break down any connective tissue in the meat thus acting as a tenderizer
There are references to acid in Ketchup, Formic acid and Acetic acid (vinegar) The acidity of Ketchup is between 3.89 and 3.92, but it is not harmful.
You can make a tomato battery but the current is very low. It would depend on the acidity of the juice which would usually be lower than in an actual tomato. Use zinc and copper electrodes and cascade multiple juice containers + to - and so forth to get a higher voltage. You might get a very small current this way.
Depending on the acidity of the tomato sauce, or whether artificial preservatives have been added, tomato sauce can be left out at room temperature (68-72 degrees Fahrenheit) for 2-5 days. Home made tomato sauce is likely to have little to no artificial preservatives, but is preserved by the acidity of the tomatoes, the added salt, and various herbs added. Therefore, in my experience, homemade tomato sauce has not gone bad until the third night, assuming that the tomato sauce was made on the first morning. Store-bought tomato sauce may have ascorbic acid, vinegar and/or other preservatives added that allow the tomato sauce to be left out unopened for an undefined amount of time. When opened, the tomato sauce will not be affected for several days. Several of my friends never refrigerate their store-bought tomato sauce, because they use up the entire bottle within the week. However, if the tomato sauce has been excessively handled or contaminated, it may spoil withing 12 hours.
One problem in studying tomato juice is that it has an opaque red color which would interfere with the observation of the color of a pH indicator.
An acidity function is the relationship between the acidity of a solution and the concentration of its solute.
