Web15 de jun. de 2024 · 2.2: Concentration. Concentration is a general measurement unit that reports the amount of solute present in a known amount of solution. Although we associate the terms “solute” and “solution” with liquid samples, we can extend their use to gas-phase and solid-phase samples as well. Table 2.2.1 lists the most common units of concentration. WebOne g of a mixture of Na 2 CO 3 and NaHCO 3 consumes y equivalent of HCl for complete neutralisation. One g of the mixture is strongly heated, then cooled and the residue treated with HCl. How many equivalent of HCl would be required for complete neutralisation? 1. 2y equivalent. 2. y equivalent. 3. 3y/4 equivalent. 4. 3y/2 equivalent
