What is casing in writing?

Letter case (or just case) is the distinction between the letters that are in larger uppercase or capitals (or more formally majuscule) and smaller lowercase (or more formally minuscule) in the written representation of certain languages.

What are 3 weak bases?

Weak Acids & Bases

Common Weak Acids Common Weak Bases
Trichloroacetic CCl3COOH pyridine
Hydrofluoric HF ammonium hydroxide
Hydrocyanic HCN water
Hydrogen sulfide H2S HS− ion

What is a pH of 10?

Pure water has a neutral pH of 7. pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic)….What does it mean for a solution to be acidic or basic (alkaline)?

pH Value H+ Concentration Relative to Pure Water Example
10 0.001 Great Salt Lake, milk of magnesia

What is the relationship between H+ and OH at a pH of 7?

A solution at pH 7 is neutral because at that pH the number of hydrogen ions (H+) equals the number of hydroxide ions (OH-), just as they are balanced in pure water.

What pH is weak acid?

The pH of a weak acid should be less than 7 (not neutral) and it’s usually less than the value for a strong acid. Note there are exceptions. For example, the pH of hydrochloric acid is 3.01 for a 1 mM solution, while the pH of hydrofluoric acid is also low, with a value of 3.27 for a 1 mM solution….

What is lowercase in MS Word?

Sometimes abbreviated as LC, lowercase is a typeface of small characters. For example, a, b, and c is lowercase and A, B, and C is uppercase. As long as the Shift key is not being pressed and the Caps lock is not active everything typed is in lowercase….

How do you find the pH of a weak base?

The procedure for calculating the pH of a solution of a weak base is similar to that of the weak acid in the sample problem. However, the variable x will represent the concentration of the hydroxide ion. The pH is found by taking the negative logarithm to get the pOH, followed by subtracting from 14 to get the pH.

What does P stand for in pH?


Do you put a comma after a name at the beginning of a sentence?

If the name is at the beginning of a sentence, you put a comma after it. If it’s at the end, you put the comma in front. And if the name is in the middle of a sentence, commas go in front and back. This is a longstanding convention, but many people don’t use a comma after “Hi,” probably because it’s so informal….

Is the first word of a sentence always capitalized?

A basic grammar rule is that the first word in a complete sentence should be capitalized. Note that per APA Style, the first word in a complete sentence should always be capitalized….

Is pH capitalized at the beginning of a sentence?

No; it’s a symbol, not a word. ACS style guide: Do not use italic type for “pH”; “p” is always lowercase and “H” is always capitalized. Yeah, but we’re talking about the beginning of a sentence here, and we all know that the first letter of the first word of a sentence should be capitalized.

Is a pH of 0 possible?

A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0. Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.

Why is P in pH lower case?

“pH” stands for “power of hydrogen”, and the atomic symbol for hydrogen is H. The p is not capitalized because it is not an element, and capitalizing it would indicate that we were talking about phosphorous, for which P is the elemental symbol….

Where is title case in Word?

Change case

  2. Go to Home > Change case .
  3. Do one of the following: To capitalize the first letter of a sentence and leave all other letters as lowercase, click Sentence case. To exclude capital letters from your text, click lowercase.

Why is pH used instead of H+?

There are two reasons why we use the pH scale instead. The first reason is that instead of describing acidic solutions with [H+] and basic solutions with [OH-], chemists prefer to have one scale for describing both acidic and basic solutions.

How do you find the pH?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].

What does sentence case mean in Word?

Sentence case involves capitalizing the first word, first word of a subtitle, and all proper nouns. In APA Style, the titles of journal articles and books should be presented in sentence case within references….

How do you convert H+ to pH?

pH is the negative base 10 logarithm (“log” on a calculator) of the hydrogen ion concentration of a solution. To calculate it, take the log of a given hydrogen ion concentration and reverse the sign….

Which words are capitalized in a title?

Capitalization in Titles According to most style guides, nouns, pronouns, verbs, adjectives, and adverbs are the only words capitalized in titles of books, articles, and songs. Prepositions, articles, and conjunctions aren’t capitalized (unless they’re the first or last word).
