A hydronium ion is a water molecule (H2O) that has gained an extra hydrogen ion (H+), making its formula H3O+. It's often present in solutions where water is interacting with acids.
Think of the hydronium ion as a sponge at a water park. Just like how the sponge soaks up excess water, the hydronium ion "soaks up" or accepts an extra hydrogen ion from its surroundings.
Proton Donor: This term refers to any substance that can donate a proton, or H+, to another substance. In our analogy, this would be like the bucket of water being dumped onto the sponge.
pH Scale: The pH scale measures how acidic or basic a solution is based on its concentration of hydronium ions. It's like rating how wet our sponge is after it's soaked up some water.
Acidic Solution: An acidic solution has more hydronium ions than hydroxide ions (OH-). If our sponge was soaking up more and more water without releasing any, it would be similar to an acidic solution getting more and more hydronium ions.
