Answer questions 1 to 5

4. If you use the Arrhenius definition, which of these chemicals is a base? a. ammonia, NH3 b. sodium hydroxide, NaOH c. sodium carbonate, NazCO3 d. water, H20

D Question 8 A solution has a hydrogen ion concentration measured by chemical means. It has a concentration of H+ 3.46 X 106. What is the pH value of the solution?

E' E a. a. C6H5NH2 (aq) + H₂O (l) C6H5NH3* (aq) + OH- (aq) When you measure the concentrations of the ionized substances you find them to be: [C6H5NH₂] = 0.234 mol/L [C6H5NH3*] = 2.8 x 10-5 mol/L [OH-]= 2.8 x 10¹5 mol/L If the Kb is 4.27 x 10-10, is the reaction at equilibrium? If not, which direction does it need to move (right or left) to reach equilibrium? Explain. At equilibrium the concentrations of the ionized substances are: [C6H5NH₂] = 0.0537 mol/L [C6H5NH3*] = 4.79 x 10¹ mol/L [OH-]= 4.79 x 10-6 mol/L If this reaction is taking place in a 2.0L container, and 1.5 moles of phenylamine were added to the reaction, what will the new concentrations of the three ionic species be when equilibrium is re-established? CoHsNHz(aq) + H₂O (l) 2. Determine the K₂ for the above solutior 3. Determine the pH for the above solution 누 C6H5NH3+ (aq) + OH- (aq)

KOH can be classified as?   Question 12 options:   A base     A metal   An acid     A carbonate

Please help

Help me solve this please

Identify the following as acids, bases or neutral solutions. a. Acidic [OH] = 3.5 x 10-2 b. Neutral (H30*) = 1.5 x 10-5 C. Basic pH = 12 [OH]= [H30*]
