Which is the chemical formula of hydrobromic acid?

Based on the equation and the information in the table, what is the enthalpy of the reaction?

Explain what happens at the saturation point when adding salt to water at room temperature.

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
