1.	At 298 K temperature, there are acids and its K_a value are as under. HF(3.5xx10^(-4)),CH_3COOH (1.74xx10^(-5)),HClO(3.0xx10^(-8)),C_6H_5OH (1.3xx10^(-10)),HCOOH(1.8xx10^(-4))Arrange these acids in decreasing order of their acidic strength.
Answer» Solution :If the VALUE of `K_a` is high then ACIDIC strength is high HF `gt` HCOOH `gt CH_3COOH gt HClO gt C_6H_5OH` `larr K_a` and acidic strength INCREASE `larr`
