1. how would the following errors affect the calculated % composition of sodium chloride, ammonium chloride & Sand?

2. give formulas for ions in the following iconic compounds?

3. why would discrepency occur in an origonal sample weight vs 3 compents recovered weight?

1. how would the following errors affect the calculated % composition of

Would it increase it, decrease it or would it remain the same? Explain! (a) Failure to remove all the NH4Cl. (b) Some solution of NaCl was splattered out of the evaporating dish in step 16. (c) The sand/filter paper was not washed after filtering the salt solution in step 13. 2. Give the formulas for the ions in the following two ionic compounds that you worked with in this lab. The bromide ion (made from bromine atoms) has the same charge as the chloride ion. Write the chemical formula for the following two ionic compounds where the bromide ion is substituted for the chloride ion. ammoniumbromide=sodiumbromide= How does the total of the 3 components you recovered compare with the original sample weight? (See step 23 in the Procedure). List at least 3 reasons why a discrepancy may occur
