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?
