salt does have lots of sodium, but it’s balanced out with other minerals, like magnesium, calcium, potassium and more than 60 other trace minerals. Salt activates enzymes needed for proper digestive processes and is required by the parietal cells of the stomach wall to makehydrochloric acid. ...
While cleaning surfaces, it's important to be careful with handling bleach; improper use or mixing with certain chemicals can make bleach toxic. The chlorine in bleach is the same as the chlorine in drinking water and in a swimming pool. In fact, you can use chlorine bleach to treat a sw...

battery acid and lemon juice. Diluting an acid decreases the concentration of H+(aq) ions, which increases the pH level of the solution towards 7, making it less acidic. However, the pH level of an acidic solution cannot become greater than 7, because the water you add to dilute it is...
2) How to prepare dilute H2SO4 (Sulfuric Acid) from concentrated H2SO4 We like to help, but you have to ask more complete questions. Perhaps we're facing a language barrier, but science should allow us to work past that, in someway. We have to know what concentration you have, and...
s highly acidic environment. If you don’t have enough stomach acid, many of the pathogens that would normally be destroyed may survive the stomach and make their way into the rest of the GI tract. (10) This can lead to chronic gut infections, impaired digestion, and an increase in IAP...
