Cobalt is a metal.
Cobalt is a metal.
Ph-O-CH2-CO-CH3
Normal CO2 in the blood is the same as Normal PH. Ph is 7.35-7.45 CO2 is 35-45
pure water (distilled) is neutral , It's Ph= 7
15.4 * 103 at 260 nm pH 7.5
The answer depends on the concentration in the original HCl-sol'n.Let this be Co (mol HCl/Litre). According to dilution 'law': Co.Vo=Cdiluted.VdilutedCdiluted = Co*10.0 ml / 50 mL = 0.20*Co mmol/ml = CdilutedHCl is a monoprotic strong acid, meaning [HCl]:[H3O+] = 1:1H3O+ = concentration HCl solution = Cdiluted = 0.20*Co mmol/ml= 0.20*Comol/LpH = -log10[H3O+] = -log10[0.20*Co] = 0.70 - log10[Co]
Cobalt hydroxide, Co(OH)2, is basic, or alkaline, so its pH will be greater than 7.
The pH level of the environment and the temperature can both affect enzyme activity. Enzymes have an optimal pH and temperature range within which they function most effectively, and deviations from these ranges can reduce enzyme activity.
A pH of 0 corresponds to a H+ concentration of 1.0 x 10^-0 M, a pH of 7 corresponds to a H+ concentration of 1.0 x 10^-7 M (neutral), and a pH of 14 corresponds to a H+ concentration of 1.0 x 10^-14 M.
I have find the answers in shandong taihe water treatment co., ltd. www.thwater.net The EDTMPA is the acid type,which is crystal powder,the PH is acid. The EDTMPS is the normally product in china ,it means EDTMPA.NA8.the PH is alkaline The EDTMPA NA5 is the product normally used in the world.the PH is neuter.
When CO is dissolved in water, it forms carbonic acid (H2CO3) through a reversible reaction. This reaction can impact the pH of the water, making it more acidic. Carbonic acid then dissociates into hydrogen ions and bicarbonate ions, contributing to the overall chemistry and equilibrium of the water.
I would checkout Jenco pH meters available at its co-op store at http://www.Supplycloud.com/jenco . A low cost but very advanced model is the Jenco 618C (or 618F).
