pH 102.12
pH balanced refers to a product that ranges from pH of:
4.5 to 5.5
pH Balance
4.5-5.5 ---- average pH range of hair , skin & nails
pure water
A neutral substance--- the positive and negative ions balance each other out
A solution that has more positive hydrogen ions than negative hydroxide ions is:
Acidic
On the pH scale, numbers less than 7 indicate a/an:
Acidic solution
RESTORE
Alkaline products should restore the pH balance once the service is complete
On the pH scale, numbers greater than 7 indicate a/an:
Alkaline solution
Alkali
Decreases concentration of hydrogen ions when placed in water because it accepts combines with H+ ions
Solution is neutral when it has:
Equal number of positive and negative ions
pH RATING
In order for a product to have a pH rating, it has to be tested for pH- which must contain water & or have the ability to dissolve in water
Indicator liquid
Indicator paper use color changed to indicate pH - well known indicator paper= Litmus
pH scale
Left side: increasing acidity { H+} Acid (0) Middle side: neutral (7) Right side: increasing alkalinity {OH-} (14) Scale: left to right 0 -14
Solution is acidic if it has:
More positive hydrogen ions the negative hydroxide ions
Distilled water with a pH of 7 is considered:
Neutral
When a solution has an equal number of hydrogen and hydroxide ions, the solution is considered:
Neutral
pH
Potential hydrogen
Numerical measurement
That indicates the acidity or alkalinity of a water based substance
pH balanced: MAINTAIN
The pH balance of the hair, skin and nails at the 4.5 to 5.5 pH range
Substances of acidic or alkaline nature dissolve in water and or contain:
Water
Solution is alkaline if it has:
more negative hydroxide ions
The most accurate method of measuring pH is with:
pH meter
Acid
- increases the concentration of hydrogen ions when placed in water because it donate or releases H+ ions
pH meter
- most accurate - an electrode is placed in the substance to be measured and an immediate pH reading appears - It can also measure the pH of the acid mantle that codes for skin and hair
A pH of 5 is how many more times acidic than a pH of 6?
