Rubber surface was modified: new chemical and simple treatments based on calcium hydroxide or acetic acid solutions were applied. The effect of the above treatments was compared with that produced by sulphuric acid or sodium hydroxide solutions or by the use of plain rubber particles, already ...
To determine the correct arrangement of different substances with increasing pH values, we need to understand the pH scale and the nature of the substances involved. The pH scale ranges from 0 to 14, where:- A pH less than 7 indicates an acid.

Acetic acid could also represent a starting point in the synthesis of C3 compounds wherein CO is the only source of carbon. Thus, condensation with formaldehyde leads to acrylic acid esters (equation 107). Alkoxycarbonylation of chloroacetic esters leads to malonates (plus an equivalent quantity ...

1% acetic acid plus sucrose is only slightly attractive, and 1% glycolic acid, citric acid, or lactic acid and sucrose are strongly appealing to the flies. To address whether the different preferences to the same concentration of acid were functions of the pH or the carbon backbone, we allowed...

Samples (20 mg) were heated with 2 mL of 0.1 N sodium hydroxide (NaOH) in a 50 °C water bath for 30 min with intermittent mixing. After neutralizing with 2.5 mL of 0.1 N acetic acid, 0.5 mL of a digestive enzyme mixture containing 1000 U of α-amylase (from Bacillus licheniformis,...
