What is the pH of a 0.140 M solution of oxalic acid?
14For any acid pH always
What is the pH value of electricity?
Electricity itself has no pi-Hydronium (pH) number. pH is a property that only applies to electrolytes (ionic compounds: acids, bases, and salts) dissolved in a water solution. It is a result of partial disassociation of water molecules under the electrostatic influence of the ions of the solute material(s) into hydronium (H3O+) and hydroxyl (OH-) ions.
Why might color on a pH strip not change?
Because the cemicals such as litmus has a special acid in it that makes it change color to the level of pH i s in the substance Booboo Because the chemical litmus makes the pH paper change color according to the pH in the substance. the main reason for the change in color of pH paper is the presence of chemical known as flevin.
What is the pH of an aqueous solution if the concentration of H plus equals 0.00097?
pH s calculated as the negative log10 of the hydrogen ion concentration. So log10 of 0.000724 = -3.14 so pH= 3.14
What is the purpose of phenolpthalein?
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
What s a pH value of 1?
acid
What is the pH of a 0.140 M solution of oxalic acid?
14For any acid pH always
What is the name for a substance in the pH scale that is under 7?
It`s called acid(such as HCl,,,,PH=1)
Is NO3 a base or acid?
NO3- is a pH neutral ion as it s the conjugate base of a strong acid.
Which is the most acid likely pH for a solution of a weak acid?
Depends what acid and s*it. What concentration you got is a big part. You can use pH = -log[H+]. But don't be silly, give us some info.
What part s of the digestive system have secretion with a pH of 2?
The stomach, particularly the acid that the stomach makes, typically has a pH of around 1 to 2, the lowest of the digestive system.
the pH level of greg´s bodliy fluids is low. what does that mean?
his fluids are acid -apex
Can limestone be used to lower water PH?
No, lime is a base chemical not an acid compound. Acids lower Ph, base raises Ph. Besides limestone is s stone not lime.
Is shoe polish an acid or base?
Everything that doesn't contain water doesn't really has a pH value: Almost every acid ONLY gives free its H+ ion(s) in water and not in non-polar 'solvents' like oil and fatty substances like wax. So it isn't very reasonable to speak of (or ask for) the pH of shoe polish.
What is a neutralzation reaction?
A neutralization reaction occurs between an acid and a base. As you may know, acids have a pH between 0 and 7, neutral substances have a pH of 7, and bases have a pH between 7 and 14. In a neutralization reaction, the pH's of the reactants are such the product(s) has/ have a pH of 7.
Is mustard is acid or base?
Mustard is a colloid/mixture with a composition of various ingredients. They range from common ingredients such as salt, vinegar, water, flour and more. Try to be careful of classifying it immediately as an acid or base; but on the pH scale mustard ranks in the lower 3-4's (7.0 pH), classifying it in acids.
Why does the pH of Coca-Cola change when you place limestone in it?
Why does the pH of coca-cola change when you place limestone in it? Coke contains citric acid. The citric acid reacts with the limestone, producing calcium citrate and carbon dioxide (bubbles) and water. The equation below shows the carbonate ion bonding with the acid H on the front of the citrate ion. As the Acid H+1's are removed from the solution, the solution becomes less acid. The pH increases. 2H3C6H5O7 + 3CaCO3 = Ca3(C6H5O6)2 + 3H2CO3(CO2 + H2O)
