Lemon juice is more acidic. Lemon juice has a pH of 2, which is very acidic. Sodium hydroxide is alkaline, with a pH of 14. However, I'd consider sodium hydroxide considerably more dangerous, as even a small splash can cause painful burning.
Yes it is. The pH of water is neutral or 7, and lemon juice is a very low 1 or 2. With the water, the resulting pH is more neutral and less acidic than lemon juice alone.
If fruits count, lemons limes, grapefruit. Anything that might have lemon juice on it (well, that's obvious.) Maybe vinegar would make the dish itself acidic. As lemon juice, lime juice might be even more powerful. As a side note, people only need to eat little foods with acid. typically, it's what you put on the food that makes it acidic.
