In addition to the picture above, acids feel sticky to the touch, like syrup.
Next, we discussed Arrhenius acids and bases. Arrhenius acids are acids that produce hydrogen ions in a solution. Arrhenius bases are bases that produce hydroxide ions in a solution. So, when put in a solution, the compound that they are a part of breaks apart and either increases the hydrogen or hydroxide concentration in the solution, depending on what is dissolved.
According to the pH scale, the lower the pH, the higher the hydrogen ion concentration in the solution. On the other hand, the higher the pH, the higher the hydroxide ion concentration.
We also learned about Bronsted- Lowery acids and bases. According to this definition, acids donate a proton and bases accept a proton. In B.L. definitions, we also have conjugate acids and bases. Acids produce conjugate bases and bases produce conjugate acids. You can see this in the picture below:
