Hydrocholoric acid is very dangerous when concentrated (at around 6N or 6 Normal) but becomes less so the more you dilute it with water. Diluting 6N HCl twofold will make it 3N, which is still very acidic. Once it is diluted less than 0.1N, it is much less dangerous - but test it with litmus paper, not your hand!
