Awhite solid can be purified from lemon juice. this solid tastes sour. when placed into water the solution conducts electricity and has a ph of 3.0. the solution turns litmus paper red. when the white powder is reacted with sodium hydroxide, a different white powder is formed which tastes salty. what kind of substance is the original white powder isolated from lemon juice?

Explanation:

When a solution is acidic in nature then it means its pH range is from 1 to 6.9. And, in an acidic solution there are more number of hydrogen () or hydronium () ions as compared to hydroxide ions ().  

Some properties of acids are as follows.

Now, since the white solid substance isolated from lemon juice shows all the properties of being an acid.

Thus, we can conclude that the original white powder isolated from lemon juice is an acidic substance.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
