Unformatted text preview: 2 is added to 0.400 L of 0.500 M aqueous HBr. The solution that remains is still acidic. It is then titrated with 0.500 M NaOH solution, and it takes 98.5 mL of the NaOH solution to reach the equivalence point. What mass of Zn(OH) 2 was added to the HBr solution? 5 . A 10.000-g zinc plate was put into an aqueous solution prepared from dissolving 0.500 g of a solid mixture of copper(II) nitrate and silver(I) nitrate in 100 mL water. After all chemical reactions in the system were completed, the zinc metal plate was taken out, cleaned, and weighed. The mass of zinc metal in the plate became 9.881 g. How many grams of silver nitrate were there in the mixture?...
