  2. Aspartame - Wikipedia

    en.wikipedia.org/wiki/Aspartame

    The stability of aspartame under heating can be improved to some extent by encasing it in fats or in maltodextrin. The stability when dissolved in water depends markedly on pH. At room temperature, it is most stable at pH 4.3, where its half-life is nearly 300 days. At pH 7, however, its half-life is only a few days.

  3. Aspartic acid - Wikipedia

    en.wikipedia.org/wiki/Aspartic_acid

    Aspartic acid (symbol Asp or D; [4] the ionic form is known as aspartate), is an α-amino acid that is used in the biosynthesis of proteins. [5] The L-isomer of aspartic acid is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins.

  4. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    When an acid is dissolved in water, the pH will be less than 7, while a base, or alkali, will have a pH greater than 7. A strong acid, such as hydrochloric acid , at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide , at the same concentration, has a pH of 14.

  5. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    To ensure consistency and repeatability, the methods use in the chemical analysis of water samples are often agreed and published at a national or state level. By convention these are often referred to as "Blue book". [4] [5] Certain analyses are performed in-field (e.g. pH, specific conductance) while others involve sampling and laboratory ...

  6. Water testing - Wikipedia

    en.wikipedia.org/wiki/Water_testing

    Water testing being conducted at a treatment facility in Broken Bow, Oklahoma. Water testing is a broad description for various procedures used to analyze water quality. Millions of water quality tests are carried out daily to fulfill regulatory requirements and to maintain safety. [1] Testing may be performed to evaluate:

    Because aspartame is about 200 times sweeter than sugar, the amount of aspartame needed to sweeten one 12-ounce can of diet soda is very small — only about 192 milligrams, or 0.007 ounces. How ...

  9. Acid neutralizing capacity - Wikipedia

    en.wikipedia.org/wiki/Acid_neutralizing_capacity

    Acid-neutralizing capacity or ANC in short is a measure for the overall buffering capacity against acidification of a solution, e.g. surface water or soil water.. ANC is defined as the difference between cations of strong bases and anions of strong acids (see below), or dynamically as the amount of acid needed to change the pH value from the sample's value to a chosen different value.
