Is 5 over 7 greater than or less than 7 over 14?
greater than
Net charge of histidine in pH 1 3 5 11?
pK1 = 2.3, pKr = 6, pK2 = 9.7 (all approximate) at physiological pH, histidine has no net charge. at pH 1, below all pKas and charge is +2 at pH 3, amine group proton pops off, so +1 charge at pH 5, still below 6 and above 2.3 so +1 charge if had pH above 6, for instance... at pH of 8 net charge is zero, or neutral... such that it is neutral at physiological pH (a bit above a pH of 7) at pH 11, exceeds all pKas of amine, acid group, and R group. So net charge of -1 amine deprotonation, carboxylic acid deprotonation, and R group deprotonation happen pH 11 because it exceeds all pKs
Are 7 and 11 equivalent?
No. 7 is 4 less than 11, and 11 is 4 more than 7.
What is two more than five?
Seven
What is seven more than the number y?
Y + 7 = 7 more than y.
Do alkalis have a pH less than 7?
no they alkaline solutions have a pH higher than 7
How can you tell how strong acids and alkalis are using the pH scale?
Acids have a pH under 7, alkalis have a pH bigger than 7.
What is the pH range of solutions which are alkalis?
Alkalines, or bases, have a pH greater than 7 (maximum is 14).
What is pH value of alkali?
The pH value of alkali substances is typically above 7, indicating that they are basic. Alkalis have a pH value greater than 7 but less than 14. Examples of alkalis include ammonia, sodium hydroxide, and potassium hydroxide.
What pH do Alkalis have?
Any aqueous solution that has a pH value greater than 7 can be considered alkaline. A strongly alkaline aqueous solution usually has a pH of at least 10, and aqueous solutions of very strong alkalies can have a pH range above 13.
What makes alkalis alkalis?
Look on the pH scale. Below 7 are acids, above 7 are alkali's!! ;-)
Are acids and alkalis the same?
No, acids and alkalis are not the same. Acids are compounds that release hydrogen ions when dissolved in water, whereas alkalis are compounds that release hydroxide ions when dissolved in water. Acids have a pH less than 7, while alkalis have a pH greater than 7.
What is the pH range of numbers is alkali?
The pH range for alkali substances is typically between 7.1 and 14. Alkalis have pH values greater than 7, indicating their basic nature.
What is the difference between acids and alkalis for kids?
Acids taste sour and can be found in foods like lemons, while alkalis taste bitter and are found in substances like soap. Acids turn blue litmus paper red, while alkalis turn red litmus paper blue. Acids have a pH of less than 7, while alkalis have a pH of more than 7.
What is the difference between an acid and an alkali?
Acids are substances that release hydrogen ions (H+) when dissolved in water, while alkalis are substances that release hydroxide ions (OH-) when dissolved in water. Acids have a pH less than 7, while alkalis have a pH greater than 7. They are chemical opposites and neutralize each other when mixed together.
What is the pH of an alkali?
If something is alkalic, it is higher that 7 on the pH scale
What is the difference between an acid and a alkali so i can do homework?
Acids have a low pH range of 1 - 6.9 Alkaline have a high pH range if 7.1 - 14 7.0 is neutral. Acids contain hydrogen. Alkaline contain hydrooxide particles. Acids have a sour and a sharp taste. Alkaline have a bitter taste.
