Help for question 5 and do 6 if possible ### Questions on Solution pH and Dissociation5. **Sodium phosphate, $ \text{Na}_3\text{PO}_4 $**, is an ingredient of some preparations used to clean walls before they are painted. What is the pH of 1.0 M $ \text{Na}_3\text{PO}_4(aq) $? [Use Table 7.4 “Stepwise Dissociation Constants for Several Common Polyprotic Acids.”]6. **a)** Is an aqueous solution that is 0.10 M $ \text{Na}_2\text{S} (aq) $ likely to be acidic, basic or pH neutral? Explain. **b)** Is an aqueous solution of ammonium cyanide, $ \text{NH}_4\text{CN} $, likely to be acidic, basic or neutral? Explain.> For any further inquiries regarding dissociation constants or chemical properties, students should refer to the appropriate tables or resources provided in their course materials.

QUESTION 10 (4b-401-1.53-1) An intern working in a research lab knocks over a beaker containing an important solution. The beaker originally contained 1.50 L of a 1.53 M solution, but after it spilled it only contained 1 L of solution. The intern decides to hide his mistake by refilling the beaker to contain 1.50 L again by adding pure water (not realizing that this will dilute the solution). What is the new concentration of the solution? Show all work and give your answer with three sig figs. Click Save and Submit to save and submit. Click Save All Answers to save all answers.
