ph testing\nph is one of the most common variables looked at in water testing. it is a measure of the hydrogen ion (h+) concentration in the sample. ph ranges from 0 - 14, with 7.0 considered neutral. solutions with a ph below 7.0 are considered acidic, and those with a ph above 7.0 are considered alkaline or basic.\nprocedure\n1. use a pipette to fill a test tube with 10 ml of the sample water.\n2. add 2 drops of ph indicator solution.\n3. swirl the test tube to mix the solution\n4. compare the test tube to the key provided to match the color of your sample to a color standard. there are two sides to the key, so be sure to compare your sample to both sides. record the ph.\nph: \n5. circle the ph quality of the stream:\nph\npoor <5.5 fair 5.5 - 6.5 good 6.5 - 7.0 excellent 7.0 - 7.5 good 7.5 - 8.5 fair 8.5 - 9.0 poor >9.0\n6. why are too high and too low ph levels detrimental to the health of a stream?\nuse these images to help you understand the effects of ph

Answer

Brief Explanations:

Los niveles de pH demasiado altos o bajos en un arroyo son perjudiciales porque afectan la supervivencia y el bien - estar de los organismos acuáticos. Un pH bajo (ácido) puede causar daño a las branquias de los peces y a otros organismos acuáticos, e incluso puede disolver los esqueletos de los invertebrados marinos. Un pH alto (básico) puede causar daño a las membranas celulares y alterar la disponibilidad de nutrientes en el agua. Además, los cambios bruscos en el pH pueden causar estrés en los organismos y reducir su capacidad para reproducirse y sobrevivir.
