catalysts, biomedical, and environmental remediation. Dilute hydrochloric acid (HCl) is a commonly used inorganic acid with strong acidity. The reaction between Ferric oxide and dilute hydrochloric acid is a common chemical reaction
We did an experiment using dilute hydrochloric acid & sodium thiosulphate and I asked why we didn't need to wear gloves. I was told it was because the HCl was very diluted and therefore not harmful if you got it on your hands. The concentration of HCl(aq) was 2M (ie, I think, 73g...
There is a lot of misinformation out there, but either way, the acid you mention is fairly dilute, and I wouldnt THINK it would prove fatal, the stomach lining would protect against the acid, except perhaps, if the throat were perforated by long-standing contact with the HCl, or the vapo...
What is the concentration of an HNO3 acid solution, if during titration with NaOH, 44.10 mL of the acid requires 73.80 mL of 0.3600 M NaOH to reach the equivalence point ? In a titration, 25.0 cm3 of 0.100 mol/dm3 sodium hydroxide solution is exactly neutralized by a dilute solution of ...
You have a 15 M stock solution which you would like to dilute 1:5 four times. What is the final concentration of the solution in mM (millimoles)? With reference to the concentration gradient (of solutes), in what direction does water move? How does the movement of water compare to...

not and cannot. Sharks, however, are an exception, maintaining bodies that are hypertonic to sea water. They achieve this through two main methods: They retain an unusual amount of urea in their blood, and the urine they excrete is very dilute, or hypotonic, compared to their internal ...
