well citric acid
use oranges
No, it can't. Acid will burn and erode your hair- DO NOT TRY IT.
Oranges have citric acid in them like most citrus fruits, and since the skin around your mouth is sensitive, the acid irritates it and it becomes red and sore.
They are like oranges, so they probably can, but in moderation. I wouldn't feed them to baby guinea pigs just in case it does harm them. You can ask a vet to make sure.
Guinea pigs can eat small amounts of oranges as a treat, but they should not be a regular part of their diet. Make sure to remove any seeds and peel the orange before offering it to your guinea pig, as these parts can be a choking hazard. Feed oranges in moderation to prevent digestive issues due to their high sugar content.
To burn things and make us live longer
Guinea pigs can eat oranges a few times a week, maybe 2 or three times. Some younger guinea pigs don't like them very much, though. Just make sure they are getting a good vitamin C supplement.
To make citric acid at home, you can extract it from citrus fruits like lemons, limes, or oranges. Squeeze the juice from the fruits and then add calcium hydroxide to create calcium citrate. This can then be reacted with sulfuric acid to precipitate citric acid, which can be filtered and dried.
Oxides of nitrogen (NOx), a combustion by-product, combine with water to form acid. The acid irritates your eyes.
because your body naturally produces acids which can burn your thought so the alkali neutralises the acid to make it not a strong acid
Eating oranges will only make you slim temperarly.
