Citric acid should be added to tomato ketchup during the cooking process, typically after blending the tomatoes and before simmering the mixture. For one kilogram of tomatoes, a common recommendation is to use about 5 to 10 grams of citric acid, depending on the desired acidity and preservation needs. This addition helps enhance flavor and acts as a preservative, extending the shelf life of the ketchup. Always adjust according to personal taste preferences and recipe guidelines.
The level of acid in ketchup (catsup) mainly depends on the amount of vinegar (acetic acid) used, the other major constituents being tomato solids, sweeteners, salt, and spices. The pH normally varies from 3.89 to 3.92 for commercial brands. Originally the term ketchup was applied to condiments with a base of mushrooms or even walnuts. Modern ketchup uses ripe tomatoes, which increases the thickness over ketchup made with unripened tomatoes.

As a percentage of the whole, I'm not sure. But it will be pretty high because there is the acid from the tomatoes and the acid from the vinegar in ketchup.
