extremely easy. Sorry! pH=1 and pOH = 13
Nope. Tricky question.
Suppose you take 1 L of each. That gives you 1 L x 0.025 mol/L HCl = 0.025 mols.
1L x 0.075 mol/L HBr = 0.075 mols.
Total mols = 0.025+0.075 = 0.1 mol but what's the volume? The volume is 2L so
M = 0.1 mol/2.0L = 0.05 M for H^+. Take pH and pOH from that. I get about 1.3 and 12.7.
