CHEMISTRY PAPER 1 HERE
GodOfWar:
lool no barium nitrate is in the test tube not HCl. You add HCl to it, its pH will decrease from i gess 7 around 2. And no ppt will be formed cuz the BaCl2 produced will dissolve .

noh dude. nitric acid WONT be formed at all !!
The equation goes like this:
BaNO3 + 2HCl --> BaCl2 + H2O + NO2
