Explanation / Answer

Acidity of acids can be explained by using their pKa values. If pKa is greater then its acidity is lower. SO acid with higher pKa value will be least acidic.

Among the given acids H2O2 is least acidic and HNO2(nitrous acid) is most acidic.

Order of acid strength of acids from least acidic to most acidic.

0.001 M hydrogen peroxide (pKa=11.75) < 0.01M hydrocyanic acid(pKa=9.31)

< 0.01M acetic acid(pKa=4.75)<0.01M nitrous acid (pKa=3.40)
