Read the excerpt from "Mother Tongue." Lately, I’ve been giving more thought to the kind of English my mother speaks. Like others, I have described it to people as “broken” or “fractured” English. But I wince when I say that. It has always bothered me that I can think of no other way to describe it other than “broken,” as if it were damaged and needed to be fixed, as if it lacked a certain wholeness and soundness. How does Tan build a central idea of her story in the excerpt? Tan discusses her thoughts about language to build the idea that the English language does not have words to match some Chinese terms. Tan discusses her relationship with her mother to build the idea that mothers and daughters in all cultures often have misunderstandings. Tan discusses her mother’s use of English to build the idea that a form of language can be purposeful and meaningful even if it is nonstandard. Tan discusses the English language to build the idea that there is a lack of appropriate synonyms for the word “broken.”

test pH test for acidity. The first answer to this question, I would like to explain that rn. pH is the number Convention from 0 to 14 that describes the acid-base prsolution properties. The smaller the number the higher the acidity of the substance, and the larger the number, the most basic. The terms "acid" and "base", which are chemically relative here, as some substances (water in particular) can be acids and bases (actually, pure water is, by definition, has a pH of 7 is considered neutral). pH emerges to take the first check the base 10 of the Hydrogen ion concentration H+, which is:. log [concentration H+]. It will give a negative value for this concentration, as a rule, tiny. Because we want a positive value multiplied by a negative sign, or:. -log concentration of H+]. There is also a value called pOH, that is based on the concentration of hydroxide ions OH-, which arise in similar form, but the opposite scale, where low values mean pOH, lower acidity and higher basicity .. In practice, we use electronic devices or liquid indicator that changes color to indicate the pH value is determined.. it is Now important to understand one important aspect of the pH scale. Because we take the logarithm of concentration of H+ ions, and then mutiplying with a negative sign, the transition from the values, say from 1 to 2 on the pH scale, concentration of H+ decreases by a factor of 10. Otherwise, if we the value of the 2: 1, the concentration of H+ increases by a factor of 10. And if we 3 in 1 on the pH scale, actually, we have an increase in H+ (that is, heartburn), 100.. the simplest rule is to find an integer, the difference between the highest and lowest value of pH, and then up 10 to this power. This is the factor where the smallest value that is more acidic than larger. Again, keep in mind that the lower the pH, the more acidic, but this value increases 10 times for each value down.. human blood is slightly basic, or about 7.4 on the pH scale. However, the stomach is usually very acid (about pH 2), while the small intestine is a bit more basic (>7). Most natural organisms, which contain buffers, which are pairs of its weak acid, conjugate/database to act to "buffer" or to minimize the pH change is always a base or acid is added. However, all tampons have a pH range in which, indeed, buffer; outside this range (either very acidic or basic), not so useful..Acid (pH less than 7) and bases (pH above 7) should be treated with great caution. To reduce the acidity or basicity, should be reduced, the H+ or OH - ion concentration, which is usually done by adding large amounts of water. The more water, the less concentration, and therefore less acidity/basicity. People can also use any type of protection or "antacids", that really is a weak base that "neutralizes" the acid.
