WebProperties of Acids. 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. WebCheck with you specification to find out exactly what you require. Acids are hydrogen ion donors. When they react, they release H + ion (s). Bases neutralise acids. They are hydrogen ion acceptors. When they react, they accept H + ions. Some bases are known as alkalis. They contain the OH - ion and are soluble in water.
