What pH would indicate and acidic soil?
The answer to 'What pH would indicate and acidic soil?' is 5. 5 is a week number and 1 is the strongest, 7 is neutral and 14 is a strong alkali 9 is week.
What description best characterizes a soil having a pH between 4 and 9?
too acidic for most plants
How do fertilizers affect the pH of the soil?
Effects Soil pH affects the amount of nutrients that are soluble in soil water and, therefore, the amount of nutrient available to plants. Some nutrients are more available under acid conditions while others are more available under alkaline conditions. However, most mineral nutrients are readily available to plants when soil pH is near neutral. The development of strongly acidic soils (pH less than 5.5) can result in poor plant growth as a result of one or more of the following factors: low pH, aluminum toxicity, manganese toxicity, calcium deficiency, magnesium deficiency, and low levels of essential plant nutrients such as phosphorus and molybdenum. ...MORE iron is more availeble in acidic soils of PH 5.5-6.5. lots of pottasium fertilizers like KCl can raise PH to 8-9 gypsum can be used to neutralize acidic soil black coffee leftovers can be used to acidify the soil
If the pH is 9 what is the concentration of hydroxide ion?
pH= -log[H+] where [H+] denotes the conc. of H+ ion. => 9= -log[H+] =>-9= log[H+] =>10-9= [H+] [OH-]= 10-14/10-9 = 10-5
What is the pH value of calcium Iodide?
A 10% solution of calcium nitrate has a pH of about 6.0. Calcium nitrate is the primary source of water soluble calcium in hydroponics. Prolonged use in other growing media can result in a gradual increase in pH because the negatively charged nitrate ions are taken up faster than the positively charged calcium ions.
What pH would indicate and acidic soil?
The answer to 'What pH would indicate and acidic soil?' is 5. 5 is a week number and 1 is the strongest, 7 is neutral and 14 is a strong alkali 9 is week.
What is the pH of pine oil?
the pH would be 7 - 9
How does a solution with a pH of 7 compare to a solution with a pH of 9?
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
A pH level of 9 is considered a weakly basic or weakly acidic?
Weak base.A pH of 7 is considered neutral, any higher (7-14) is considered basic, lower (1-7) is considered acidic.
Would you expect the pH of an solution of soap to be 4 or 9?
9
What description best characterizes a soil having a pH between 4 and 9?
too acidic for most plants
What would you predict the pH of the water to be following the reaction with sodium?
It would form NaOH which would mean it is alkaline as it is an hydroxide, and it would have pH 9
What is the pH of soap 4 or 9?
The pH of soap typically falls within the range of 8 to 10, so it would be more accurate to say that the pH of soap is closer to 9 than to 4. However, the pH can vary depending on the specific formulation and ingredients of the soap.
How much stronger is pH 9 than pH 4?
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
Would you expect the pH of a solution of soap to be 4 or 9?
9
Do strong bases have a pH below 7?
No. Strong bases wold have a pH above 8 or 9. A pH of 13 would be a very strong base.
A solution with pH of 9 is?
A solution with a pH of 9 is a weak alkaline.A pH of 9 is a weak base. The concentration of H+ ions contributes to the pH of a substance. As the pH number goes up, the concentration of H+ ions goes down.It directly translates to pHx= 1x10 to the power of -x moles per liter.
