pH Levels

CuSO4 is a salt of weak base(copper hydroxide) and strong acid(sulphuric acid)....the Ph of the solution of cuso4 will be acidic....

Since HNO3 is a strong acid, it completely dissociates in solution. HNO3 -> H+ + NO3-. Therefore, the concentration of H+ ions is the same as the concentration of the HNO3 solution, 0.0067M. pH = -log[H+] = -log(0.0067) ≈ 2.18. pOH = 14 - pH ≈ 11.82.

To determine the pH of a substance using the pH method, you will need a pH meter or pH strips. For a pH meter, simply immerse the electrode into the substance and wait for the reading to stabilize. For pH strips, dip the strip into the substance and compare the color change to the provided chart to determine the pH value.

0 - 6.9

The lower the pH number the higher the concentration of hydronium ions and higher the strength of acid

A substance with a pH of 13.0 is considered highly basic. This pH level indicates that the substance is strongly alkaline.

no! it is both the measurement of the substance's acidity and basicity.

Maalox has a pH range of about 6 to 9, depending on the specific formulation.

The chemical equation for the neutralization reaction of potassium hydroxide (KOH) with nitric acid (HNO3) is: KOH + HNO3 → KNO3 + H2O This reaction produces potassium nitrate (KNO3) and water (H2O).

You can test pH levels using pH test strips, a pH meter, or pH drops. Simply dip the test strip into the solution, or submerge the meter's probe, or add a few drops of the liquid to a small sample. The color change or reading will indicate the pH level of the solution.

Since a perfectly neutral liquid such as distilled water has a pH of 7, a liquid with a pH of 7.1 is just very slightly alkaline. Perhaps it has a bit of soap in it.

It depends on the molar concentration (Number of moles per liter of solution, a mole is 6.022X1023 formula units). Since it is a strong base that gives one hydroxide ion per formula unit, the pH of an RbOH solution is equal to 14 + the logarithm of the molar concentration. So a 1.0M solution has a pH of 14, a .1M solution has a pH of 13 and so on until a pH of about 7.

A strong base like sodium hydroxide or bleach has a pH of 14. This means it is highly alkaline and can cause severe chemical burns or damage to skin and surfaces.

CH3NH3Cl->CH3NH3+ + Cl¯

Cl¯+H2O-> Doesn't reactor!

CH3NH3+ +H2O <-> CH3NH2 + H3O+

(c-x) M x M x M

H2O + H2O <-> H3O+ + OH¯

y M y M

[H3O+]w= (x+y) M

[OH¯]= y M

Like this: [H3O+]>[OH¯] => Acid

To lower the pH of a solution with a pH of 12.5, you can add an acid such as hydrochloric acid, sulfuric acid, or phosphoric acid in small increments while monitoring the pH level until it reaches your desired range. It's important to do this slowly and carefully to avoid overshooting the target pH. Remember to wear appropriate safety equipment when handling acids.

Lower pHs are more acidic

Higher pHs are more basic.

Therefore, the pH of 5 will be more acidic than pH of 7 **

also, the pH of 7 is neutral.

Edit by Kelvin876: Higher pHs are alkalines.

**Each number lower is 10 times greater in acidity than the prior number. This would mean that a solution with a pH of 5 is 100 times greater in acidity compared to a solution with a pH of 7.

Nylon is a polymer insoluble in water so it can not change the pH value of water which is 7.

The pH of K2SO4 is close to neutral, around 7. This is because K2SO4 is a salt that is fully dissociated in water, resulting in the formation of K+ and SO4^2- ions, which do not significantly affect the pH of the solution.

The pH of walnuts is typically around 6.0 to 6.5.

Gaviscon typically has a neutral pH level of around 7.0.

The PH Scale for Paraffin is 7, hope this helped you!

The pH of moisturizers typically ranges between 4.5 to 6.5, which is slightly acidic to neutral. This pH range is considered suitable for skin health as it helps maintain the skin's natural acidity and protective barrier.

The optimum pH for chymotrypsin is around pH 8.0 - 9.0. This alkaline pH range is ideal for the enzyme to exhibit its maximum activity and efficiency in catalyzing peptide bond cleavage. Deviations from this pH range can result in reduced enzyme activity.

7 is neutral

below 7 is acidic

above 7 is basic

therefore a pH of 5 is more acidic as a pH of 9

One common cause of increased pH levels in bread is the presence of excessive amounts of alkaline ingredients such as baking soda. Additionally, over-fermentation of the dough can lead to an increase in pH due to the production of basic compounds. Finally, contamination with alkaline substances during the baking or storage process can also cause an increase in pH levels in bread.

hydrochloric acid and battery acid have a pH of about 1

hope that helped!
