Is there a link between the strength of an acid and its reactivity? What is an Acid? An acid is a Chemical Substance with a pH less than seven. They are generally very sharp and sour, and they react with metals, producing hydrogen. Some examples are Nitric Acid, Citric Acid, Sulfuric acid, and many more. What is a Base? A Base is an Alkaline Solution that has a pH above 7. Bases react with acids to form salts; this process is called neutralisation. Some examples are Sodium hydroxide, Calcium Carbonate or Potassium Oxide, among many others. Bases that are soluble in Water, are called Alkalis. The pH Scale The pH scale is used to determine the strength or different Acids and Bases. The pH scale runs from 1 through to 14 with 7 being water. Any substance with a pH under 7 is an Acid and any pH over 7 is a Base. Strength in Acids Strength in Acids vary depending on their ions. The more ions or more concentrated the ions are determining an acid's strength. Reactivity in Acids Reactivity in acids work by each acid's ions mixing with each other, but some acids will have more ions than others, this is the strength of an acid. These ions are both greater in numbers and more concentrated in stronger acids, or in acids with a lower pH. If a reaction is taking place, you will most likely be able to see or hear it, as often, a reaction may produce smoke...

or bubbles, and you may hear a fizzing sound. Is there a link between the strength of an acid and its reactivity? So, Using the information we have found out about the pH scale, strength in acids, and reactivity in acids, we can answer the final big question. Well, Acid's strength is measured in the pH scale, and we know that all acids are under 7, in the scale. We also know that from 7, the lower the pH, the stronger the acid. Stronger Acids, with a pH around 1, 2 or 3 will tend to react quicker, because of the very highly concentrated H+ions, which increase the frequency of collision, while with a weaker acid, the rate of reaction is slower as there are less H+ions to react and collide more. In conclusion, there is a link between an acid's strength and reactivity and therefore the pH and the reactivity: A stronger acid with a lower pH will react fastest that a weaker acid with a higher pH.

This Know is a research project on whether the strength of an acid affects its reactivity, but along the way, has lots of key information about Acids and Alkalis, and acts as a good summary. There is still a lot to know about this unit.
