a)
Interpretation: Three common strong acids should be determined.
Concept introduction: Substances that are dissociated in water to produce hydrogen or
Strong acids are acids that are completely dissociated in aqueous solutions to form hydrogen ions. Weak acids are only partially ionized to form hydrogen ions in aqueous solutions.
b)
Interpretation: Three common strong bases should be determined.
Concept introduction: Substances that are dissociated in water to produce hydroxide or
Strong bases are bases that are completely dissociated in aqueous solutions to form hydroxide ions. Weak bases are only partially ionized to form hydroxide ions in aqueous solutions.
c)
Interpretation: Characteristic behavior of strong acid or strong base should be determined.
Concept introduction: Substances that are dissociated in water to produce hydrogen or

- If a powdery substance is added to a fluid in a beaker and the following reactions occur: rising bubbles to the top of the fluid that smell bad when they burst, and heating of the mixture; what reaction has occurred?arrow_forwardWhich of the following is an example of a chemical reaction? Group of answer choices (a) Not enough information to say for certain (B) A metal glows green when heated (c) A white solid is dissolved in water. The solution emits heat as the solid dissolves (d) Gas bubbling from a bottle of soda when it is opened (e) A compound turns from red to yellow when heated (and back to red when cooled)arrow_forwardAn ore is O a mixture of two or more metallic elements. O a natural source from which a metal can be extracted A pure metal naturally found on earth.. a soluble mixture of ionic compounds.arrow_forward
- . An aqueous solution of sodium carbonate, Na2CO3, is titrated with strong acid to a point at which two H1 ions have reacted with each carbonate ion. (a) If 20.0 mL of the carbonate solution reacts with just 40.0 mL of 0.50 Macid, what is the molarity of the carbonate solution? (b) If the solution contains 5.0 percent by mass sodium carbonate, what is the density of the solution? (c) Suppose that you wanted to prepare a liter of an identical solution by starting with crystalline sodium carbonate decahydrate,Na2CO3?10H2O, rather than with solid Na2CO3 itself. How much of this substance would you need?arrow_forwardContainers A and B hold two aqueous solutions. Container A has Hydrochloric acid with a concentration of 1.0 mol/L. Container B has Sodium Hydroxide with a concentration of 2.0 mol/L. Container A Container B (a) Samples from both containers are mixed together and react. What are the products of the reaction? (b) 300 ml. of solution is taken from Container B. How many moles of Sodium Hydroxide are in this sample? (c) What volume of solution from Container A will exactly neutralise the 300 ml sample from Container B?arrow_forward'(d) sodium cnionae is an ionic compound. ltcontains sodium ions, Na+ and chloride ions, CI-When molten sodium chloride is electrolysed, sodium metal and chlorine gas are formed.
