Anonymous users2024-02-13Summary. Hello, it is a pleasure to answer your questions, and the specific answers are as follows:
Because although perbromate acid (HBRO4) and perchloric acid (HCO4) are both strong acids, n-periodic acid (H5IO6) is a weak acid, and periodic acid (HIO4) is a strong acid, so it is not included in the six strong acids.
The six strong acids in chemistry are nitric acid, sulfuric acid, hydrochloric acid, perchloric acid, hydrobromic acid, and hydroiodic acid; The four strong bases are potassium hydroxide, sodium hydroxide, barium hydroxide, and calcium hydroxide.
Why is perbromoic acid and periodic acid not included in the six strong acids?
Hello, I am happy to answer your questions, and the specific answers are as follows: because although perbromate acid (HBRO4) and perchloric acid (HCO4) are strong acids, but orthoperiodic acid (H5IO6) is a weak acid, and periodic acid (HIO4) is a strong acid, so the six strong acids in chemistry are nitric acid, sulfuric acid, hydrochloric acid, perchloric acid, hydrochloric acid, hydroiodic acid, hydroiodic acid; The four strong bases are potassium hydroxide, sodium hydroxide, barium hydroxide, and calcium hydroxide.
I hope it can help you, if it helps you, please give a like, thank you. (・

Anonymous users2024-02-12Periodic acid is not a strong acid. N-periodic acid, chemical formula H5io6, dehydration to obtain orange high Si Brigade shouting iodate HIO4, further dehydration to form I2O7 and finally to obtain iododioxide. Used as an oxidant, it should be noted that although iodine, bromine and chlorine are halogen elements, and perbromine and perchloric acid are strong acids, but orthoperiodic acid is a weak acid, and perperiodic acid is a strong acid, and the reason can be explained by the empirical law of Pauling acid and alkali.

Analysis: At room temperature, the periodic acid (H5IO6) solution with pH 2 was mixed with NaOH solution of pH 12 in equal volumes, and the mixed solution was acidic. The iodic acid (HIO3) or permanganic acid (HMNO4) solution was mixed with the NaOH solution of pH 12 in equal volumes, and the mixed solution obtained was neutral.
Please ask the following questions:
1) Periodic acid is (fill in "strong acid" or "weak acid"), the reason is . In the Na5io6 solution, the order of C(IO65), C(Na), C(H), and C(OH) from large to small is .
2) Periodic acid is known to be white crystals, and the iodine-containing substances that decompose when melted are iodic acid. Write the chemical equation for the decomposition of periodic acid when it melts.
3) It is known that periodic acid and manganese sulfate (MNSO4) react in solution to form permanganic acid, iodic acid and sulfuric acid, and the oxidant of this reaction is . The ionic equation of the reaction can be expressed as . Try to compare the oxidation of periodic acid and permanganic acid.
Answer (1) Weak acid (2 points); Since the C(H) in the periodic acid solution is equal to the C(OH) in the NaOH solution, after the two are mixed in equal volumes, the mixed solution is acidic, indicating that the acid is excessive, and only a part of the molecules of periodic acid in the original periodic acid solution have been ionized, so periodic acid is a weak acid (3 points). c(na＋)、c(io65－)、c(oh－)、c(h＋)
2) 2h5io6＝2hio3＋o2↑＋4h2o
3) periodic acid (2 points); 5h5io6 2mn2 2mno4 5io3 7h2o 11h (3 points); h5io6＞hmno4
The acidity of hydroiodic acid, hydrobromic acid, hydrochloric acid, hydrofluoric acid, and hydroiodic acid is a strong acid.
Although HF is very corrosive and can corrode glass, it is not completely ionized in water and is a weak acid.
1.Determination of the amount of concentration of a known substance and the pH of a weak acidIf the acid Hb is known, the concentration of the substance is, if it is a strong acid, it is completely ionized, pH = 2; If it is a weak acid, the pH > 2 >>>More
Household flour is ordinary flour, and the general gluten strength is relatively moderate, so it should belong to the category of all-purpose flour. Because household flour is widely used, it is necessary to make a variety of delicacies with different tastes, such as bread, steamed buns, noodles, cakes, etc., and the gluten and protein content of all-purpose flour are relatively moderate, and it can be used to make fluffy texture and fluffy texture. 2. Flour can wait for different parts of the wheat to be ground according to different gluten flour, which is generally divided into high-gluten flour, all-purpose flour and low-gluten flour, high-gluten flour is suitable for making food with a fluffy taste, such as bread, low-gluten flour is suitable for making soft food, such as cakes, and all-purpose flour has a wide range of applications and can make a variety of delicacies with different tastes. >>>More
