Will acetic acid cause irritation on our skin? Does it have any specific smell? what is it's pH range? Is it too strong to cause irritation in our nasal passage?

It totally depends on the concentration of acetic acid you use. We have dilute acetic acid in our kitchens (vinegar) so low concentration (Approx 3-9% v/v) is okay. The smell is acidic but is bearable. The pH of vinegar is around 2.4. On the opposite scale glacial acetic acid (99%), causes severe skin burns and is flammable. It has a very strong acidic smell and will most probably burn your nasal passage or severely irritate it. Hope this helps.
