The results of Rutherford's experiment were surprising as most of the alpha particles went straight without any deflection
<h3>Rutherford's Gold Foil experiment:</h3>
During the experiment, Rutherford directed beams of alpha particles at the thin gold foil and observed the following things:
Most of the alpha particles passed straight without any deflection
Few alpha particles got deflected from their paths on small angles
Very few alpha particles got deflected from their paths on very large angles
<h3>Results of the experiment:</h3>
Most of the space inside an atom is empty
The center of the atom is occupied by a tiny positively charged dense body called a nucleus. Most of the mass of the atom is concentrated in the nucleus
The electrons revolve around the nucleus in circular orbits and are called planetary electrons
Thus, the results of the experiment were surprising due to the above-stated facts.

Answer: The strength of an acid or alkali depends on the degree of dissociation of the acid or alkali in water. The degree of dissociation measures the percentage of acid molecules that ionise when dissolved in water. He could use universal indicators or litmus paper for this.
