1) According to Bronsted-Lowry theory

acids are _________
bases are _________

this is my last problem! please someone help!

This isn't in your text/notes.

The first half is
According to this theory, acids are proton donors.
So bases must be proton ........?

no it isn't in my notes. And bases are proton acceptors

According to the Bronsted-Lowry theory of acids and bases, acids are substances that donate protons (H+ ions) while bases are substances that accept protons.

To determine whether a substance is an acid or a base, you need to look at its behavior in a chemical reaction. If a substance donates a proton (H+) to another substance, it is classified as an acid. On the other hand, if a substance accepts a proton (H+), it is considered a base.

For example, in the reaction between hydrochloric acid (HCl) and water (H2O), the HCl donates a proton to water, forming hydronium ions (H3O+). In this case, HCl is the acid because it donates a proton.

Similarly, in the reaction between ammonia (NH3) and water (H2O), ammonia accepts a proton from water, forming ammonium ions (NH4+). In this case, ammonia acts as a base because it accepts a proton.

By understanding the Bronsted-Lowry theory and observing the protons' movement in a reaction, you can determine whether a substance is an acid or a base.

Surely it's in your text. You're right. Bases are proton acceptors according to the Bronsted-Lowry theory of acids/bases.
