Acids have pH values of below 7, have a sour taste (when edible) and are corrosive. Acids are substances that can neutralise a base, forming a salt and water. When acids are added to water, they form positively charged hydrogen ions (H +) The presence of H + ions is what makes a solution acidic. Example: Hydrochloric Acid. Web1.
