HW: p. 491(1-7)
1 . Assess the general homes of stomach acids with the basic properties of bases. Acids:
Aqueous solutions of stomach acids have a sour flavor.
Stomach acids change the color of acid-base signals.
Some acids react with active precious metals and relieve hydrogen gas, H2. Stomach acids react with bases to produce salts and water.
Stomach acids conduct electric current.
Aqueous solutions of bases taste bitter.
Basics change the color of acid-base indicators.
Dilute aqueous solutions of bases think slippery.
Basics react with acids to produce salts and water.
Facets conduct electric current.
2 . a. Distinguish between binary acids and oxyacids when it comes to their element elements as well as the systems utilized in naming these people. b. Offer three samples of each type of acid.
-- Binary acids contain L atoms (which are released as H+ when the acid is dissolved) and a straightforward anion such as Cl- or Br -- or S2-, while oxyacids contain H atoms and an oxyanion such as SO42- or NO3-. Two samples of binary will be hydrochloric and hydrofluoric acid, and two examples of oxyacid are sulfuric and nitric. 3. Determine and describe the feature properties of five common stomach acids used in market. Give a few examples of the standard uses of each. 4. Though HCl(aq) exhibits properties of the Arrhenius acid solution, pure HCl gas and HCl blended in a nonpolar solvent exhibit none of the properties of your Arrhenius acid solution. Explain so why. - HCl(g) consists of covalently bonded elements that may ionize. non-polar solvent substances don't catch the attention of HCl substances to lead them to be ionized. 5. a. What distinguishes strong acids from poor acids?
-- Strong stomach acids ionize completely in water down aqueous option, while on the other hand, poor acids ionize much less than 100%.
n. Give two examples each of good acids and weak stomach acids.
-Strong=HCl and HNO3
Weak =HF and H3PO4
6. H3PO4, which contains three hydrogen atoms per molecule, can be described as weak acid solution, whereas HCl, which is made up of only one hydrogen atom per molecule, is actually a strong acid solution....
