The phrase "acidic acids" is not correct and is redundant in written English.
It is not usable because "acidic" already implies a certain type of acid, making the term unnecessary.
Example: "The solution contained various acidic acids that affected the pH level."
Alternatives: "acidic solutions" or "strong acids".
Low amount of acidic acid (0.5 M) was used and dibasic sodium phosphate (DSP) was introduced as ionic crosslinker to improve nanofibres water stability and to neutralize the acidic pH of electrospun membranes after fibres soaking in biological fluids.
And then there may also be A minus, which in the case of acetic acid would be acetate, -- -- where we have two electronegative oxygens, among which the negative charge can be shared and the acetate ion, which is the conjugate base of acidic acid.
Acidic acid is used as a stimulator in dyeing process to adjust pH 3 4 (Chiou et al. 2004).
The determination of soluble silicates in seawater is based on the reduction of a silicomolybdate in acidic acid solution to 'molybdenum blue' by ascorbic acid which is read colorimetrically at 660 nm.
Following incubation, 3 ml of fixative (1∶3 glacial acidic acid to absolute methanol) was added to each culture, mixed by inversion and centrifuged at 1200 rpm for 10 minutes.
For labeling with mAb to myosin heavy chain (MF20), cultures were fixed with a mixture of 3.5% formaldehyde, 70% ethanol and 5% acidic acid and washed thoroughly before incubation with antibody.
After 4 6 weeks incubation the cells were fixed with methanol and acidic acid solution (10%), and stained with ethanol (20%), crystal violet (0.4%); the colonies were scored and large and small colonies were counted.
For quantification of the colonies, crystal violet was dissolved in 10% acidic acid and OD 595 nm was measured.
They were transferred to nitrocellulose filters and detected by staining with Amido Black (0.1% in 25% isopropanol and 10% acidic acid).
In brief, high molecular weight chitosan (2.5%, w/w) was dissolved in a blend of glycerol (10%, w/w) and acidic acid (2.5%, w/w), respectively.
The cells on the bottom surface of the Transwell insert were fixed with 75%methanol/25%% acidic acid for 20 min and stained with 0.25% Coomassie blue in 45%methanol/10%% acetic acid for 20 min.
