    Probably, but a very dilute solution is pH=.

    However, the pH of the general solution NaOH solution is above 10.

    For example, 1mol l of sodium hydroxide.

    Solution pH = 14

    10mol l of sodium hydroxide solution 15

    Hope it helps you o(o

    It depends on how much NaOH is at your concentration, NaOH is an alkaline substance, and the pH value of water is theoretically, and theoretically NaOH can be configured with a solution greater than any pH value; However, due to the dissolved carbon dioxide in the water, it may be slightly higher, but it is entirely possible to prepare a solution.

    Yes, greater than 7 less than or equal to 14 is alkaline, and the pH value is different if the concentration is different.

    Assuming that the NaOH concentration is C, the pH of the solution is (14+LGC), and 14 is the ionization equilibrium constant of water.

    In principle, a very dilute NaOH solution can be.

    Its concentration can be calculated according to the ionization equilibrium of water as 10 (to the power of the power) mol l, which is mol l

    It is generally about 10, it can be 8·8, and the pH value can be a decimal.

    Possibly, the pH depends on the NaOH concentration.

    1. Sodium hydroxide with a concentration of 1%.

    Solution pH:

    Hydroxide ions can be calculated.

    The concentration is calculated by density per water and is slightly smaller. )。

    then ph=14-poh=14+.

    Sodium hydroxide. The solution is alkaline, and the pH of the alkaline solution is greater than 7 The role and use of sodium hydroxide are:

    1. Sodium hydroxide is an inorganic compound, and the use of sodium hydroxide is to provide an alkaline environment or as a catalyst. Sodium hydroxide is very soluble in water, and sodium hydroxide is very versatile, but when sodium hydroxide is applied, the industrial sector will treat it accordingly according to the situation of sodium hydroxide itself.

    2. Sodium hydroxide will be used in the production process of soap, paper, detergent, etc. Sodium hydroxide is used in many organic reactions, because all kinds of uncontrollable things can happen at any time, when making soap, paper, and detergents, the factory will handle and apply it according to the situation.

    3. Sodium hydroxide is corrosive, and you need to pay attention to your own safety when applying. In industry, sodium hydroxide is commonly known as caustic soda, because the concentrated sodium hydroxide solution splashes on the **, which will corrode the epidermis and cause burns.

    Sodium hydroxide is used in the production of polycarbonate.

    Super absorbent polymer rollers, zeolites, epoxy resins.

    Sodium phosphate, sodium sulfite.

    and one of the important raw materials for a large amount of sodium salt.

    Sodium hydroxide does not have a pH value, the pH value is the sodium hydroxide solution, and the pH value of the sodium hydroxide solution is related to the concentration.

    The pH of the solution of sodium hydroxide depends on the NaOH concentration. Assuming that the NaOH concentration is C, then the pH of the solution is (14+LGC), and 14 is the ionization equilibrium constant of water.

    From the point of view of the original bridge failure, the very dilute NaOH solution can be dismantled widely.

    Its concentration can be calculated according to the ionization equilibrium of water as 10 (to the power of the power) mol l, which is mol l

    The pH value is a general technique, which is the negative logarithm of the concentration of hydrogen ions in sodium hydroxide.

    ph=-lg[h+]

    Of course, sodium hydroxide is a strong base, and there are very few hydrogen ions in the solution, so it can also be better to use poh to represent the loss.

    1000g of 5% concentration of NaOH solution, the body stool volume is about 1L of its jujube field powder, the concentration of sodium hydroxide material ridge rock is:

    pH = 5 hydrogen from the mu mold base slow concentration = 10 -5 add sodium hydroxide.

    First neutralized as a neutral solution pH = 7

    Suppose the volume of the raw liquid is 1000 ml.

    Sodium hydroxide volume number = 1 10 -5 liters = ml.

    Then adjust the pH to 8 hydroxide ions.

    The concentration is 10 -6 mol liters.

    v = 10 - 5 liters = 10 - 2 ml = ml.

    Total = ml.

    In fact, the pH value is hydrogen ions.

    If the concentration of hydrogen ions is negative to the (-5) power, then the pH value is 5

    Due to hydrogen ions and hydroxide ions.

    The sum of the products is 10 to the power of (-14), so when the pH value is 8, where the concentration of hydrogen ions is 10 to the power (-8), then the concentration of hydroxide ions is to the power (-6) of 10, then the concentration of NaOH is to the power (-6) of mol l

    I don't know the density and temperature, I can't find it.

    Suppose the density is p(g l).

    Then the mass of 1 L solution is P(G), which contains NaOHP 1000(G), which is P40000

    mol), the concentration of hydroxide is p 40000 (mol l), then at 25 degrees Celsius, the concentration of hydrogen ions is 4*10 -10 p (mol l), so pH = 10 lg4 p

    If the density of the solution at low concentrations is approximately equal to the concentration of water, then pH = 10 LG4 =

    Sulfuric acid is acidic (H2SO4) solution, the concentration of C(H+) is larger, the concentration of sodium chloride is neutral (NaCl), C(H+) and C(OH-) concentrations are the same, sodium hydroxide is alkaline (NaOH), C(OH-) concentration is larger, and the concentration of C(H+) is smaller. ph=-lg

    c(h+) neutral aqueous solution c(h+) = -7th power cycle.

    -7 power of acidic aqueous solution C(H+)>.

    Alkaline water-soluble rotten forest liquid c(h+) of the -7th power.

    So, pH(H2SO4)<7, pH(NaCl)=7, pH(NaOH)>7

    The concentration of C(H+) in the acidic (H2SO4) solution is larger, the concentration of sodium chloride is neutral (NaCl)C(H+) and C(OH-) is the same, the concentration of sodium hydroxide is alkaline (NaOH)C(OH-) is larger, and the concentration of C(H+) is smaller. ph=-lg

    c(h+) neutral aqueous solution c(h+) = to the power of -7.

    -7 power of acidic aqueous solution C(H+)>.

    Alkaline aqueous solution c(h+) to the power of -7.

    The blind age is based on pH(H2SO4)<7, PH(NaCl)=7, pH(NaOH)>7

    The 5% concentration is 5 times 10 to the 3rd power, so the pH is 14-3=11

The process waste left between the punching parts and between the punching parts and the side of the strip during nesting is called lapping. The function of lap is to compensate for positioning errors and shearing errors to ensure that qualified parts are punched out; the second is to increase the stiffness of strips, facilitate the feeding of strips, and improve labor productivity; At the same time, the lap can also avoid the burr on the edge of the strip during punching, and the gap between the molds can be improved, so as to improve the life of the mold. The lap value has a great impact on the hedging process and the quality of the punching part, so it is necessary to reasonably determine the lap value. >>>More
