You realize Table Salt, which is typically iodized, is not the same as uniodized sea salt? Right? Table Salt is not NaCl, usually it's I2NaCL. Sea Salt, is purified NaCl, typically.
You are extremely mistaken as to the amount of iodine in iodized salt. If table salt were I2NaCl, it would be quite toxic. I'm not sure who told you that's the composition of table salt, but they're completely wrong.
Whether it's sea salt or table salt, they are both around 98-99% NaCl, meaning that they are, for all purposes relating to acid-base balance in your body, identical.
