WebApr 18, 2024 · It depends on the precision of the answer. Little of the carbonate goes to bicarbonate, so to two significant figures you really don't need the quadratic solution. √(2 × 10 − 4) × 0.5 = 0.010 so that solution is off by about 1 part in 50. Seems good enough. – MaxW Jul 30, 2024 at 23:04 @MaxW I edit my answer your comment makes the … WebSodium Carbonate Solution 1.0M MSDS # 648.10 Section 1: Product and Company Identification Sodium Carbonate Solution, 1.0M ...
