True or false: to avoid a violent reaction and splattering while diluting solutions, always pour concentrated solutions into water or into less concentrated solutions, while stirring.

True.

To minimize reaction and splattering, it is better to pour the higher concentrated solution into lower one. Higher concentration mean that the solution is heavier so it will be easier to spread. Stirring also help to distribute the solution, avoid violent reaction and reduce the splatter. Always remember to wear appropriate protective device when  working in the lab.

b would be the right answer
