Laboratory Experiment 2: Alkalinity and Acidity - IIT Delhi


Mineral acidity: It is measured by titration to a pH of about 3.5, the methyl orange end point (also known as methyl orange acidity). Total acidity: Titration of a sample to the phenolphthalein end point of pH 8.3 measures mineral acidity plus acidity due to weak acids, thus this is called as total acidity (or phenolphthalein acidity).

Determination of Titratable Acidity in Wine or Juice


Titratable acidity in grape juice or wine is by convention expressed as g/L tartaric acid, although of course the actual acidity is a mixture of acids, predominately tartaric and malic, but also citric, succinic and trace amounts of other weak and strong acids.

G1599 Understanding GMPs for Sauces and Dressings


Acidity and pH The acidity of a food is indicated by its pH value. The pH scale (Figure 1) ranges from 0 to 14, with pH 7.0 being neutral. Any pH below 7.0 falls in the acidic range while those above pH 7.0 are in the basic range. The lower the pH reading, the more acid is the food.

Increasing ocean acidity can also damage corals, as well as fish . and other marine species. Ocean acidity has increased by about 25 percent in the past three centuries, and it is likely to increase another 40 to 50 percent by 2100. As the ocean becomes more acidic, corals are less able to remove minerals from the water to buildir the skeletons.

Water requirements for sheep and cattle


Acidity or alkalinity (pH) Water with a pH value below 6.5 (acid) or above 8.5 (alkaline) can cause digestive upsets in stock, resulting in rejection of the water, depressed appetite and consequent loss of production. If this problem is present, animals may perish, even when they apparently have adequate water.
