A drop of a liquid sample was put on the pH paper. It was observed that the colour of the pH paper turned blue. The liquid sample islemon juicesodium bicarbonate solutiondistilled waterhydrochloric acid
A colourless liquid sample was tested with pH paper strip. The colour of the strip changed to reddish pink. The sample could be :
Which is more acidic: a solution of pH = 2 or a solution of pH = 6?
The pH of a river water sample as measured by pH paper is found to be 6. What does it tell us about water?
Which is more basic (or more alkaline): a solution of pH = 8 or a solution of pH = 11?
(a) What does the pH of a solution signify? Three solutions A, B and C have pH values of 6, 4 and 10 respectively. Which of the solutions is highly acidic?(b) A farmer has found that the pH of soil in his fields is 4.2. Name any two chemical materials which he can mix with the soil to adjust its pH.
While doing drill Rohan was asked to about-turn. After two, minutes he was again asked to about-turn. How many degrees did Rohan turn in the activity?
A sample of soil is mixed with water and allowed to settle. The clear supernatant solution turns the pH paper yellowish-orange. Which of the following would change the colour of this pH paper to greenish-blue? Lemon juiceVinegarCommon saltAn antacid
What is the meaning of pH?
When the strip of pH paper was put in a given solution, the pH paper changed to orange red. The given solution is most likely to be of :(1)sodium hydroxide(2) hydrochloric acid(3)sodium bicarbonate(4)ethanoic acid
What is the pH of a neutral solution?
Give one example each of a salt which gives an aqueous solution having :(a) pH less than 7 (b) pH equal to 7 (c) pH more than 7
What is the name of the indicator which can be used for testing the pH of a solution?
In an experiment to measure the pH values by using a universal indicator, a student found that the pH values of four given solutions A, B, C, and D are 10, 6, 2, and 14 respectively. The solution which will require the maximum volume of sodium hydroxide solution for complete neutralisation is solution :(1) A (2) B (3) C (4) D
