The pH scale ranges from 1 to 14, with 1 being extremely acidic, 7 being neutral, and
14 being extremely alkaline. The pH of the egg white will be lower than that of the over cleaner.
Strong alkali things are also called strong bases, and they have high pH values. (about 10 to 14). Fat and carbon are easily dissolved in reaction with alkaline solutions. This is why alkaline detergents (pH: 12-14) are very efficient in cleaning greasy ovens. The more alkaline the oven cleaner, the better the results you'll get.
But good/powerful oven cleaners should contain more essential ingredients (besides being alkaline) in order to be effective!
It should have the ability to cling to the oven walls and to dissolve carbon in cold action.

Weak alkali things, or weak bases, have pH values slightly greater than 7 (7 to about 10)
Neutral water is of course pH 7. Weak alkali detergents are usually not suitable for removing baked-on fat (carbon) from soiled oven.
Slightly acidic things have a pH slightly below 7 (4-7), and strong acids have pH below that (0-4).
What else can I help you with?
Which lake have a higher elevation or a lower elevation to dissolved mineral?
Higher elevation is going to also have higher atmospheric pressure. My recollection is that the higher pressure of the atmosphere on the surface of the lake will cause a higher level of absorption in the lake itself.
What is the function of the lower objective on a microscope?
The lower objective on a microscope helps to provide initial magnification of the specimen. It typically has a lower magnification power compared to the higher objectives. This objective is usually used for scanning the specimen and locating areas of interest before moving to higher magnifications.
The bone that hold your lower teeth?
The lower teeth are held in place by the mandible, which is the bone forming the lower jaw. It is a strong and movable bone that houses the teeth on the lower part of the face.
IS The movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called diffusion?
No, the movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is not called diffusion. Diffusion is the movement of substances from an area of higher concentration to an area of lower concentration. The movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called filtration. Filtration is a passive process driven by the pressure difference across a membrane.
Which solution contains a higher concentration of solvent that the solution it is being compared with?
The solution with the higher concentration of solvent compared to another solution would be the one with a lower concentration of solute. The solvent concentration is higher in the solution where the solute concentration is lower.
Are the waves produced by the magnesium ion flame test of a higher or a lower frequency than the visible spectrum?
For the alkali metals, higher atomic number results in a lower wavelength flame test color. If the alkali earth metals follow the same trend then magnesium should have a higher wavelength (LOWER FREQUENCY) than the visible spectrum.
Is sour milk more of an alkali then milk?
Sour milk is more acid than nomal milk. Lower pH = acid. Higher pH = alkali.
What is more dangerous concentrated alkali or dilute alkali?
Concentrated alkali is more dangerous than dilute alkali because it has a higher pH and can cause more severe burns and damage upon contact with skin or tissues. Dilute alkali, on the other hand, is less corrosive and poses a lower risk of harm.
Why alkali metals are strong reducing agent?
Alkali metals are strong reducing agents because they have a tendency to lose their outer electron easily, forming a stable cation. This electron donation ability allows them to readily transfer electrons to other substances, resulting in the reduction of the other species. The lower ionization energy of alkali metals also contributes to their strong reducing properties.
Do strong acids have a higher or lower pH than weak acids?
Strong acids have a lower pH than weak acids. This is because strong acids completely dissociate in water to release all their hydrogen ions, resulting in a high concentration of H+ ions and a lower pH. Weak acids only partially dissociate, leading to a lower concentration of H+ ions and a higher pH.
What has a greater concentration of acid pH 5 or pH 3?
pH 3 the lower down the scale the high the the concentration of acid the higher up the higher concentration of alkali's.
What are denser harder have higher melting points and are slightly less active than alkali metals in the same period?
These are characteristics of alkaline earth metals, such as calcium and magnesium. They have tightly packed metallic lattices, making them denser and harder than alkali metals. Their higher melting points and lower reactivity compared to alkali metals can be attributed to their lower atomic size and increased nuclear charge.
Is the pH of a strong base lower or higher than the pH of a weak base?
Weak bases will have a higher H+ concentration.
Why are the metallic bonds in alkali metal relatively weak?
Alkali metals contribute only one valence electron
Why do alkali metals have lower ionization energies than the alkali earth metals?
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.
Would you expect strong acids or weak acids to have a lower pH level?
Strong acids would be expected to have a lower pH level compared to weak acids. Strong acids fully dissociate in water to produce a higher concentration of hydrogen ions, resulting in a more acidic solution and a lower pH.
Why does toothpaste contain a mild alkali?
Toothpaste contains alkali to neutralise the acid your teeth make so that you don't have to get fillings but it can't be too strong or it can damage your teeth too and also alkali's taste nasty.
