Labels:text | screenshot OCR: Litmus Test: The litmus test is done with a small piece of paper that has been soaked in the juice of the litmus berry. Litnius paper turns red in acids and blue in bases. (Many berry juices | change color when pH is changed including]strawberry , rasberry and others.) pH Test: The pH of a solution is a measure of the concentration of hydrogen ions in that solution. It is defined as the negative log of the H+ concentration in mol/liter. pH can be determined by an plectric pH meter or pH paper. A pH < 7 indicates an acid solution. A pH >7 indicates a basic solution. A pH =7 indicates a neutral solution, one in which the concentration of hydrogen ions is equal to the concentration of hydroxide ions. pH paper, like litmus paper, is a PH Meter small strip of absorbents paper soaked in indicato ...
