- Answer the following by selecting all correct answers. (a) Dynamic equilibrium O is a condition where two opposing processes are occurring at the same rate. O can only occur in water. O is used to describe what happens when weak acids or weak bases are added to water. O is used to describe what happens when strong acids or strong bases are added to water. (b) What will happen if acetic acid (HC2H3O2) is added to water?arrow_forwardA road tanker carrying an acid was involved in an accident and its contents spilledon the road, iron drain covers began melting and fizzing as the acid ran over them. ASpecialist was called to se if the acid actually leaked into the nearby river.(a) Explain how the specialist could carry out a simple test to see if the river water contains some acid or not.(b) The word melting is incorrectly used in the report. Suggest a better name that should have been used.(c) Explain why drain covers began fizzing as the acid rain over them.arrow_forward(a) A 50.0 mL solution is prepared to be 1.29 M acetylsalicylic acid.
