ACIDS AND BASES PH

THE PH SCALE IS USED TO MEASURE HOW ACIDIC OR BASIC A LIQUID IS. THE SCALE RANGES FROM CLOSE TO 0 – 14 ACIDS RANGE FROM 0 - JUST BELOW 7 BASES RANGE FROM JUST ABOVE 7 – 14

ACIDS RELEASE HYDROGEN (+) IONS INTO WATER TASTES SOUR ARE CORROSIVE CONDUCTS ELECTRICITY

BASES RELEASE HYDROXIDE (OH-) IONS WHEN DISSOLVED INTO WATER TASTE BITTER ARE CORROSIVE USED IN CLEANING SOLUTIONS (FEELS SLIPPERY) ALKALI IS ALSO A WORD FOR BASE
