Question
differentiate between concentrated and dilute acids
Answer
A concentrated acid is an acid which is in either pure form or has a high concentration. Laboratory type sulfuric acid (about 98% by weight) is a concentrated (and strong) acid. A dilute acid is that in which the concentration of the water mixed in the acid is higher than the concentration of the acid itself.
★The main difference between dilute and concentrated acid is the difference in the concentration of H+ ions.
★More the number of H+ ions more concentrated will be the acid.
★For higher secondary students: More the value of Ka, less the value of pKa (most probably negative values are more acidic) higherwill be the concentration of H+ and more concentrated will be the acid.
★For secondary students: The solution having pH range between 1 to 3.5 will be concentrated while the remaining range till 7 will be dilute acid. Concentrated acid can be diluted by adding water to it.
