This is not a good idea u never know what the chemicals could do when in contact with metal or pipes or even water. always ask your chem teacher and make sure they tell u before. also alert them if this has happened because they can alert the school and act as needed

Answer:

That's a major lab mistake! Never pour chemicals in sink unless otherwise stated by the lab instructor. They should go in a properly labelled waste jar or similar container. Apparatus should not be left in sink, it should be washed and cleaned, and returned to where it came from.

a water sample is found to have a cl- content of 100ppm as nacl what is the concentration of chloride in moles per liter
ladessa [460]

Answer:

The concentration of chloride ion is 2.82\times10^{-3}\;mol/L

Explanation:

We know that 1 ppm is equal to 1 mg/L.

So, the Cl^- content 100 ppm suggests the presence of 100 mg of Cl^- in 1 L of solution.

The molar mass of Cl^- is equal to the molar mass of Cl atom as the mass of the excess electron in Cl^- is negligible as compared to the mass of Cl atom.

So, the molar mass of Cl^- is 35.453 g/mol.

Number of moles = (Mass)/(Molar mass)

Hence, the number of moles (N) of Cl^- present in 100 mg (0.100 g) of Cl^- is calculated as shown below:

N=\frac{0.100\;g}{35.453\;g/mol}=2.82\times 10^{-3}\;mol

So, there is 2.82\times10^{-3}\;mol of Cl^- present in 1 L of solution.
