What happens when a solution of an acid is mixed with a solutionof a base in a test tube

A student tests the pH of a base solution and then adds 10 ml of acid to the base solution. After this, the student retests the pH of the solution. What will most likely to the pH?A The pH of the solution will increase and become more acidic. B The pH of the solution will decrease and become more acidic. C The pH of the solution will increase and become more basic. D The pH of he solution will decrease and become more basic.

(b) The table gives the temperatures of the solutions before the student mixes them. potassium hydroxide solution 17.8 °C dilute hydrochloric acid18.4 °CCalculate the mean (average) temperature of the two solutions. (2) mean temperature = .............................................................. °C(c) The student repeats the experiment on a different day, using 25 cm 3of potassium hydroxide solution and 25 cm 3of dilute hydrochloric acid.The thermometer shows the highest temperature reached at the end of the experiment. °C 25 20(i) Complete the table by giving the missing information.Give both temperatures to the nearest 0.1 °C. (2) mean temperature at start in °C temperature at end in °C temperature rise in °C5.2

When a strong acid reacts with a weak base, the resulting solution will be:

If the pH of a solution is increased what happens to the acidic solute in the solution?
