Question

Brine is a preservative for vegetables, fish, fruit, and meat. It prevents the growth of bacteria. What is the concentration in ppm of the solution made by dissolving 2.5 g of NaCl in enough water to make mL of brine solution?

 

Answer 1

Molar mass of NaCl 58.44 g/mol

Moles of NaCl$=\frac{2.5}{58.44}=0.043moles$ .

NaCl + H₂O → NaOH + HCl
