If an egg white is a weak alkali and oven cleaner is a strong alkali will the pH of the egg white be higher or lower than the pH of the oven cleaner and why?

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).

Is esr higher or lower in women who are menstruating?
It is higher.
What is alkalinity and its relation to the pH scale?
The pH scale is mostly in the range 0-14. A pH value of 7.0 means neutral. The lower the value, the more acidic the substance. The higher the value, the more alkaline. Note that, pH can be 15, just like it can be -1.
Can NaOH and pepsin cause digestion?
No is the answer. Sodium hydroxide is is such a strong alkali that it will 'burn' the cells just like acid does. So it is not found in body. Instead you have sodium bi carbonate. But you have very strong acid in stomach. Hydrochloric acid. Imagine acidity go on increasing ten times as you go from 6 to 5 and 5 to 4. And pH in stomach is 1 to 2. (Why does not stomach is 'not' charred at this pH ?) Pepsin works in high acidic pH only and almost stop working at 5.5 pH. So no question of digestion in sodium hydroxide, which is strong alkali with very high pH. If you lower the pH pepsin starts working again.
Would the loss of striatal neurons result in higher or lower GABA levels?
lower
Which group has feathers wings and strong but lightweight bones?
Lower chordates
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.
Do strong acids have a higher or lower pH than weak acids?
Weak bases will have a higher H+ concentration.
Which side of the pH scale is alkali?
Anything with a pH higher than 7 is a base, lower than 7 is acidic.
What does it mean to be a strong or weak acid or base?
a strong acid is lower on the pH scale a strong base is higher on the pH scale
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.
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.
How to lower alkali in water?
Add acid
Which is a strong acid-pH 1 or pH 6?
The Lower The pH Scale The stronger the acid ph7 is neutral and the higher the scale past 7 the stronger the alkali is
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.
What value on the pH scale represents a strong acid a strong base and a neutral substance?
Strong acid = 1 pH ( or lower ) Strong base = 14 pH ( or higher ) Neutral solution = 7 pH
Air moves from where pressure is higher to lower or lower to higher?
Higher to lower.
