What is PH?

2.What are PH values?

Do these values depend on something?  Explain your answers.

3. Check Chart 3.2 about acids and bases.

What can you explain about it?

4. What is Neutralization?  Give examples.

1  1 IS A MEASUASURE OF HOW ACIDIC OR BASIC THE SOLUTION IS

 ,  2 IS A NUMBER FROM 1 TO 14 WITH 7 AS THE MIDDLE(NEUTRAL) POINT

    VALUE BELOW 7 INDICATE ACIDITY WHICH INCREASE AS THE NUMBER DECREASE,1 BEING THE MOST ACID

       VALUE ABOVE  7 INDICATE ALKALINITY WHICH INCREASES AS THE NUMBER INCREASES              

        ,14BEING THE MOST ALKALINE

        

        3THE STRENGTH OF SOME ACIDS AND BASES DISSOCIATED TO FORM IONS

           A STRONG ACID OR BASE DISSOCIATES 100 WHILE A WEAK OR MODERATELY WEAK ONE DISSOCIATES LESS THAN 100

        

      4 NEUTRALIZATION IS THE INTERACTION THAT OCCURS BETWEEN ACIDS AND BASES IN WHICH THE PROPERTIES OF EACH ARE CANCELED OUT BY THE OTHER

          EXAMPLES

                1 TOOTHPASTE WITH TOOTH AND ACID

               2 PEOPLE SUFFER ACIDITY, THEY HAVE SOME ANTACIDS TO EAT TO NEUTRALIZE THE ACID COMING FROM THE STOMACH
