Concept Introduction:
Lewis base is compound which is electron rich. It will donate the excess electrons to the acid. Lewis acid is the compound which is electron deficient. Lewis acid contains empty orbital and accepts lone pair of electrons.
(d)
Interpretation:
The given blanks have to be filled with suitable words.
Concept Introduction:
Solubility product relates the solubility of a salt with the concentration of ions present in the salt. Solubility product holds a direct relation with the solubility of the salt. The solubility product is the ability of the solid to dissolve in aqueous solution.

- Equal amounts (moles) of HCl(aq) and NaCN(aq) are mixed. The resulting solution is (a) acidic (b) basic (c) neutralarrow_forwardThe pH values listed in Table 9.1 are generally the average values for the listed materials. Most natural materials, such as body fluids and fruit juices, have pH values that cover a range for different samples. Some measured pH values for specific body fluid samples are given below. Convert each one to [H+], and classify the fluid as acidic, basic, or neutral. a.Blood, pH=7.41 b.Gastric juice, pH=1.60 c.Urine, pH=5.93 d.Saliva, pH=6.85 e.Pancreatic juice, pH=7.85arrow_forwardOne half liter (500. mL) of 2.50 M HCl is mixed with 250. mL of 3.75 M HCl. Assuming the total solution volume after mixing is 750. mL, what is the concentration of hydrochloric acid in the resulting solution? What is its pH?arrow_forward
- Classify the solutions represented in Exercises 9.28 and 9.30 as acidic, basic, or neutral.arrow_forwardA solution of sodium cyanide, NaCN, has a pH of 12.10. How many grams of NaCN are in 425 mL of a solution with the same pH?arrow_forwardClassify each of the following as a strong or weak acid or base. a NH3 b HCNO c Mg(OH)2 d HClO3arrow_forward
- When might a pH meter be better than an indicator to determine the end point of an acid-base titration?arrow_forwardFollow the directions of Question 64. Consider two beakers: Beaker A has a weak acid(K a=1105). Beaker B has HCI. The volume and molarity of each acid in the beakers are the same. Both acids are to be titrated with a 0.1 M solution of NaOH. (a) Before titration starts (at zero time), the pH of the solution in Beaker A is the pH of the solution in Beaker B. (b) At half-neutralization (halfway to the equivalence point), the pH of the solution in Beaker A the pH of the solution in Beaker B. (c) When each solution has reached its equivalence point, the pH of the solution in Beaker A the pH of the solution in Beaker B. (d) At the equivalence point, the volume of NaOH used to titrate HCI in Beaker B the volume of NaOH used to titrate the weak acid in Beaker A.arrow_forwardWrite two BrnstedLowry acid-base reactions and show how they represent proton-transfer reactions.arrow_forward
