Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. CuBr, copper(I) bromide, 1.0 X 10 g/L Agl, silver iodide, 2.8 X 10-' g/10 mL Pb}(PO4)2, lead(II) phosphate, 62 X 10" g/L Ag2SO4, silver sulfate, 5.0 mg/mL. Ksp for AgBr is 5.0 10. Use observations to determine the structure of compound Y Observation 1 1 Addition of excess aqueous AgNO 3 to 0.6800 g of compound Y resulted in the precipitation of 0.319 g of AgBr (Mr = 187 *only bromide counter ions will form AgBr Observation 2 Treating 0.6800 g of compound with a strong dehydrating agent resulted in a mass loss . What mass of AgBr will dissolve in 500.0 mL of 5.30 M NH? To a 250.0 mL volumetric flask are added 1.00 mL volumes of three solutions: 0.0100 M AgNO3, 0.145M NaBr, and 0.100 M NaCN. Your answer should have two significant figures. You can see that in AgBr, there is 1 Silver atom and 1 Bromine atom. Most questions answered within 4 hours. AgBr is widely used in photographic films and is believed by some to have been used for making the Shroud of Turin. The balanced equation would be: 2Na_2S_2O_3 + AgBr \rightarrow Na_3(Ag(S_2O_3)_2) + NaBr Step Two: Find molar ratio between substances Using the above we can see that the molar .
