(a)
Interpretation:
Whether a precipitate will form when the given solutions are mixed should be determined along with the net ionic equation should be written, if precipitate will form.
Silver nitrate and sodium chloride
Concept introduction:
Solubility of any compound is predicted by above solubility chart.
Blank boxes indicate no precipitate formation occurs which means soluble in dilute solution.
Boxes with grey small box will form precipitate from dilute solutions and boxes where formula is written this is a cation-anion combination that will form precipitate.
Precipitation reactions: It is a type of chemical reactions where two soluble salts react with each other and formed different products, out of which one product must be insoluble in solution which is known as precipitate.
A chemical equation which shows only the species that are participated in the reaction is said to be net ionic equation.

- Arsenic acid, H3AsO4, is a poisonous acid that has been used in the treatment of wood to prevent insect damage. Arsenic acid has three acidic protons. Say you take a 25.00-mL sample of arsenic acid and prepare it for titration with NaOH by adding 25.00 mL of water. The complete neutralization of this solution requires the addition of 53.07 mL of 0.6441 M NaOH solution. Write the balanced chemical reaction for the titration, and calculate the molarity of the arsenic acid sample.arrow_forwardComplete and balance the following acid-base equations: (a) A solution of HClO4 is added to a solution of LiOH.
