In a 1.00 M HCl solution, NaCl will dissolve, but the extent of dissolution depends on the amount added and its solubility limit at a given temperature. NaCl's solubility is approximately 358 g/L at 20°C, meaning large quantities can dissolve, but exceeding this limit will result in undissolved salt. The discussion also touches on safety concerns regarding handling strong bases like NaOH, with varying personal experiences shared about skin contact and the potential for harm, particularly if it comes into contact with the eyes. Overall, the key focus remains on the solubility of NaCl in HCl and the importance of safety when working with chemical solutions.
