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.
i hope this helps you!

Answer:
Final mass of Iron bar will be 621.105 g.
Mass of rust = 126.730 g
Explanation:
Exactly one- eighth of the Iron turns to rust. That means, the mass of Iron that under go the process of rusting(
) = 565 × 
= 70.625 g
So, the mass of pure Iron after rusting will be = 565 - 70.625 = 494.375 g
Now the reaction of rusting as follows,
2Fe + 
→ 
Now, molecular weight of Iron = 55.84 g
So, moles of Iron undergoes the reaction is = 
= 1.26 mol
Molecular weight of 
= 159.68 g
Here 2 moles of Iron undergoes the reaction to produce 2 moles of Iron oxide.
Hence, 1.26 mol of Iron will produce 1.26 mole of Iron oxide.
Mass of = 
= 126.730 g
∴Mass of rust = 126.730 g
∴ Final mass of Iron bar = ( 494.375 + 126.730) = 621.105 g
